I just had a look at those ruggeduino. For the price of ONE 'ruggeduino', I can buy 45 arduino pro mini or nano copies from china. . . There's a price point where it's not worth it. Plus we learn by making mistakes.
Would connecting a DI (pull up resistance) to a GND pin destroy the arduino? I don’t have a breadboard in hand, only a breakout board and want to test out if my code is reading the DI pin correctly. Essentially doing this to mimic a button pressed when DI is connected to GND. Thank you
If you do use Vin and dont trust you self, just put a Zener Diode between, so if you do connect it the wrong way, it will just short the battery Most Offical Arduino board (Mega 2560, UNO) have this anyway
This is not really true, when it comes to I/O pins and ground. The microcontroller has internally a current limiting output driver, so it can handle a short circuit to ground without taking any damage. The current available is about 20mA. We also can see projects in the Arduino world, people connecting LEDs directly to output pins w/o any current limiting resistor. In those cases the microcontroller is delivering max. current output, into a typical 1.8V - 2.4V voltage limiting load. However, when working as inputs the absolutely maximum input voltage is 5.5V before damage. Also, the "Aref"-pin is suspectible for damage, as it's outputting the actual Aref-voltage (5V as default) when external Aref is not set. This pin must not be shorted to neither +V or GND, only float. By the way I like your videos :)
the weird thing is for me (I have 2 Clones (Mega 2560, Arduino UNO WiFi)) and a old r2 Arduino UNO Ive Shorted a I/O pin that is HIGH to GND but it never damaged the chip....
Hi, is it normal that EX and RX LEDs shine constantly very little, like dim. I worry there was a short circuit, but I can still upload programs on my Arduino. I am just bothered buy this two lights constantly shining. Thank you.
When I was a kid messing with an Arduino UNO I was trying to power a motor with Arduino PWM so no motor controller this motor would've also pulled about 500 mah. Then I had a 9 v plugged into the vin and ground. My circuit didn't really make sense lol because I didn't have any resistors at the time and I smoked the atmega chip. But surprisingly it still worked after being smoked and there was no damage as far as I could tell.
Few days ago I switched the Vin and GND cables, but I was using a USB TTL driver so thankfully the magic smoke only came from the cables that were fried 😂
Once grabbed the wrong wire and connected a 3 amp 12v power supply directly to gpio on a cheap Arduino clone when I was 14, I didn't notice until it started smoking lmao
Problem #4 can be solved by adding a diode to the PCB to prevent current from flowing in the wrong direction between the vin-pin and ground-pin. Since the schematic for the Arduino is open source, I don't know why this hasn't been implemented into the design. Is there perhaps a particular reason why they didn't add a diode to the schematic to protect the Arduino from situation #4?
my arduino rip list arduino uno R3 arduino uno R3 Smd arduino nano 33 ble arduino nano nrf need to buy some more XD btw if you wonder why so many dead arduino.s i am building high power rc car and tried using bluetooth wifi ect now i am using a 4x4 crawler with 5x mini-servos 1x big servo 1x wifi camera 3.3v boosted with antenna then arduino nano rf boosted and expansion shield and for controller joystick shield v2.4 with rf chip with boosted antenna and arduino smd 😅🤣
Rip plug the Arduino to external power source then into your pc then open Arduino idel and type a line of code and hit compile congratulations you just fried your Arduino lol
considering that all you said will only happen, if someone cant read or is extrem careless, you missed another advice to not put a weight of over 1000 pounds on your arduino or throw it into a lava pit or run it over with your car or use it under water or use it to hammer nails into a wall. common sense is recommended while using an arduino. mistakes can happen but dont act stupid.
The free course is great for total newbies. If you have programming experience, most of the stuff on actual coding will be far too simple. But here and there there is still good information about specifically coding on the Arduino, and it's a way to get familiar with the device, the IDE, and getting them to talk to each other. It's a good place to start.
I'm a beginner and actually came across the Ruggeduino webpage. I also asked what could destroy my Arduino on the Arduino.cc forums. So it's like you sensed I needed help. Thank you!
I'm looking at the Ruggeduino as a replacement to the Arduino Uno and Synthetos GShield V5 to control a shapeoko2, what GShield should match to this Ruggeduino for my application. Thank you, and great video?
Even tho' I haven't damaged my UNOs yet, your video hammered home the idea that I could. However, my solution was to purchase two blank ATMEGA328P chips and burn the Arduino bootloader to them. Now I have 2 spare chips in the off chance that I toast the chips on the board. I've been pretty careful so far but have in one instance overdriven an LED to the point of damaging the LED. I guess the LED was a cheap fuse in this case. The chips are available both pre-programmed ($5.49) and blank ($4.95) from Jameco. I had originally bought the Arduino ISP for projects I had in mind where I would program the board without using the bootloader. So now I'm a little more comfortable using the boards knowing I have spare processors tucked away. The Ruggeduino is a nice idea but a little overkill for the average hobbyist.
Perhaps someone could clarify a couple things for me. In other videos a pushbutton when pressed directly connects the 5volts out to a digital input pin, so is that power source regulated in a way that prevents overcurrent casualties? Also I have heard that a 12vdc automotive battery source can be used to power the board directly, so does anyone have experience with that?
If you set Arduino pin as an Input it has much higher resistance than pin set as Output, that's why you can directly connect it to 5v but even with this high resistance you shouldn't ever exceed the 5v limit otherwise you will damage the pin (or the entire microprocessor) too.
What if i do it like this? int Output =53; int Input = 52; void setup() { pinMode(Output, OUTPUT); pinMode(Input, INPUT); } void loop() { digitalWrite(Output, HIGH); //gives +5V to the LED (3V, if i add a resistor betwen arduino output(53) pin and the LED) digitalWrite(Input, HIGH); //does this pin connects to the GND once it's set on HIGH? } -------------------------------------------------------- //or this one void loop() { digitalWrite(Output, HIGH); digitalWrite(Input, LOW); //the LED shouldn't glow, or? } // example for 1 LED I want to drive a 4x4 LED matrix without using transistors, will it damage my arduino if i do it like that? Or do i really need to set another pin as an output and add a transistor to use it like as a switch?
The best way to protect any port on any processor is to use opto couplers but not just for over current conditions and over voltage but for other reasons too one of these being that noise Spurious bursts of noise upset and change values on port registers which can give you false readings when dealing with high switching speeds Shifting through registers and suddenly changing from output to input can equally produce the same result but for best results either use hex buffers or opto couplers and since we are moving towards fibre optic might a a good idea to do this anyway then you can move forward with that technology
I bought a Arduino last week, and as I was wiring up a 4 digit 7 segment display, I accidentally created a short circuit. Luckily one of the LED's inside the display got destroyed, and broke the connection. I have so far not notice anything wrong with the board or microcontroller, and I have tested all the pins since then.
Due to the Onboard reglator, for the the ones that have the SMD version of 7805/78L05/etc(Any 3 pin, 5V) Regulators, Technicality 7 to 40V, For best regulation(This is for all 3 pin(IN-COMMON-OUT)) is +3V above the output and shall not exceed 40V You WILL damage any 3 pin regulator going above 40V But things limit this on the arduino board, 1 - The Capacitors, there normally rated at +25V, 2 - The DC connector the way its designed, only as high as +12V There rated at 7-12V Best output go for 8-12V Also, a note, the Regulator on arduino is 1A max output
In the last week I have went through 2 arduino unos because I wanted to make a gameboy but I had a 12v battery and I plugged the bare wires into the 5v pin and the ground 😅👍
just acciedentally discharged a disconnected 36v line with a cap inside into Mega2560 Serial1 RX1 port.. RX1 TX1 is now broken and my chip has a tiny hole in it lol but rest still working. but for the price of one ruggeduino i get 8x mega2560 boards or 15x Uno's or 36x nano's , so no problem lol
Nice video, but I think that you have exagerated some things. I have done some of those things with my Arduino and it's still going strong. For example, I had switch the polarity of an ATMega328P standalone and it got very got, but in 10 minutes it was fine.
This seems like a big advertisement. My Arduino has survived short circuits - the LEDs just go a bit dim and/or the board resets. By the way, if I remember correctly, the barrel connector protects against reverse polarity.
ive actually had and have an arduino that was connected to a 12v battery and i accidentally shorted 5v to ground. the regulator fried and anctually send 7V into my usb port (another thing that they failed to protect on the original board) and both laptop and arduino (chip) survived
If you uploaded your sketch through icsp it can remove the bootloader. If you didn't use icsp to upload the sketch upload the sketch to pastebin.com and reply with the link
+zach burke The Arduino IDE crashed, so I dont have the sketch anymore. It was supposed to read RFID tags, and it does actually work, but the rx pin is fried. That means that I cant upoad to the MCU anymore. It wasnt the serial interface. It must've been static, because I have no other eplanation for it. Also the loopback test fails, but the oscilloscope reads the data happily.
David Serrano as I understand it arduino reboot when serial connections are made this is tied to the hard reset line. So when uploading it should reboot and not even run the code. That could be wrong I've never looked deeper then normal code.
+zach burke Not when serial connections are made. The serial chip (also an atmega) is pulling the reset line low and bringing the bootloader into programming mode when a sketch is uploaded. Im gonna investigate any involved solder joints when im back from vacation.
So is there any way to fix any of these arduinos?? Namely I did mistake 4 on accident. So is it trash now or can it be salvaged? Or is this video just an advertisement.
+fragwits Okay I have a lot of problems with button examples. After many different tests I finally go the button to react, but the LED blinks fast and when I push the button it gets steady or turn off. Which one is different. But when I use a pull down or pull up resistor to stop the LED flashing all the time, my button does not react. Before the button reacted I was wondering if the pin was broken, but I have tried input 2 and also tried input 4
I can't help but feel like some of this info is misleading... Sorry to say, not saying this was intentional, but! Shorting pins to ground/together: Done that many times before on an accident. The current draw gets so high the regulator can't cope with it and the Arduino resets, tristating the pins. Applying overvoltage to the pins: I've actually seen an Atmel document, which shows applying 220V to the digital input. (I think, don't quote me on that). Anyway-the point is, that the pins DO already have protective diodes that clamp the voltage. These can take few thousand volts, as they are designed for ESD protection. Obviously, the current needs to be limited. But my guess would be that 9V through 1k wouldn't do any damage at all... Reversing the polarity is something that's impossible to do when powering the Arduino from USB. The mistake of connecting a battery in reverse to the 5V and GND pins isn't easy to make. Putting over 5V to the 5V pin is also not an easy mistake to do...
yea, because vin is connected to a voltage regulator so it needs a voltage greater than 7v, So you might use the 5v to connect a arduino to a powerbank, usb cable
all these comments saying that with the same price they can buy 20 of them from china i would sugggest to remember that in the first place ruggeduino was created be implemented in industrial use and enviroment. if you put an arduino in an industrial situation it wont last longer. because arduino has no ESD protection no current limit protection no current limit on the pins no precision clock no protected and insulated pins no over voltages and no possibility to run from -40 to 85 degrees celsius. This is the difference not the fact that you coulf buy 10 from china at the same price, of course you could but it will last a week on an industrial enviroment and also is not even certified and protected so the price is fully justified
Not really. Nobody is more quickly irritated than I am by "click bait" that promises you something and then delivers junk. I agree that a couple of pitches are made for the ruggeduino, but the video is also full of very useful information for those who don't have a ruggeduino. I was glad I watched it.
+Jeroen vd Velden You are not paying for a logo. You are paying to people which spend their time, money and afford on this project (arduino). Why people see only parts price? I'm working on many projects, at the end there is a hardware and software part. Manufacturing costs are few Pounds, but I wouldn't bothered to working on something for manufacturing price...
+Jeroen vd Velden have a look at ebay, and use the site where the currency is low. I'll bet you'll find an original or a good copy from one of the arduinopartners for around 7 euro or less. Believe me, blowing up an arduino is not very hard to do :(
that's interesting. I've got an italian uno. I'm pretty sure that I shorted an oscillating digi out to ground for a few seconds once and it survived, so I assumed that there was some sort of current limiting built in. Not sure.

For one ruggeduino you can buy 25 Arduino Uno clones from china. You can destroy 24 learn an awful lot and still have one that works. Why would i ever by an Arduino for $50?? This is a bad ad for an overpriced product.
I've caused some serious damage to the ATMega328 on two of my UNO's from overvoltage. Don't accidentally loop 24v back to them, folks. However I am certain I can fix them by just...replacing the ATMega328 with another one from eBay for less than dollar. The chip is designed to be easily removed and replaced.
LsHallo Vader Yep. I've actually replaced the aforementioned Unos with some 101s. The 32mhz is really noticeable with what I do with them, so I'll be more careful with these. I plan to repair the Unos and use them only for testing purposes.
Why?: It is a common misconception that the Arduino 5V regulator will ensure that the 5V voltage remains at 5V, no matter what. IT WILL NOT! The only thing the 5V regulator can do is control current coming from the USB port or the external DC power jack. If the current is coming from an external power source directly connected to the 5V connector pin, the regulator can do nothing about it. Another consequence of applying more than 5V to the 5V connector pin is possible damage to the PC's USB port. If the Arduino is powered from USB then this excessive voltage can cause current to flow backwards through the voltage-switching MOSFET T1 and back to the PC's USB port.
putting aluminum inside the microwave is going to damage it, luckily the Ruggeduino..
I just had a look at those ruggeduino.

It's amazing how resilient parts can be - and in some case - how not resilient they can be!
What happens if I apply more than 5V volts to 5V pin. Which components can be damage?
I think primarily the microcontroller can be damaged.
is there an arduino alternative that's not so easy to damage? and has safeties built in?

Whats abbout any pin set up to high an go form eg. PIN-13 HIGH to RESET?

arduino uno makes high pitch whistling sound when plugging into usb?
Sir,what is the max. voltage that can be applied to the Vin?
Due to the Onboard reglator, for the the ones that have the SMD version of 7805/78L05/etc(Any 3 pin, 5V) Regulators, Technicality 7 to 40V, For best regulation(This is for all 3 pin(IN-COMMON-OUT)) is +3V above the output and shall not exceed 40V
You WILL damage any 3 pin regulator going above 40V
But things limit this on the arduino board, 1 - The Capacitors, there normally rated at +25V, 2 - The DC connector
the way its designed, only as high as +12V
There rated at 7-12V
Best output go for 8-12V
Also, a note, the Regulator on arduino is 1A max output

I can't help but feel like some of this info is misleading... Sorry to say, not saying this was intentional, but!
Shorting pins to ground/together:
Done that many times before on an accident. The current draw gets so high the regulator can't cope with it and the Arduino resets, tristating the pins.
Applying overvoltage to the pins: I've actually seen an Atmel document, which shows applying 220V to the digital input. (I think, don't quote me on that). Anyway-the point is, that the pins DO already have protective diodes that clamp the voltage. These can take few thousand volts, as they are designed for ESD protection. Obviously, the current needs to be limited. But my guess would be that 9V through 1k wouldn't do any damage at all...
Reversing the polarity is something that's impossible to do when powering the Arduino from USB. The mistake of connecting a battery in reverse to the 5V and GND pins isn't easy to make.
Putting over 5V to the 5V pin is also not an easy mistake to do...
Why would you put any kind of current to the 5 volt pin? Its for powering sensors not an input
actually you can power the arduino via the 5v pin but only if the input is 5v (duh)
Oh well okay... Is there any reason to use this and not Vin?
yea, because vin is connected to a voltage regulator so it needs a voltage greater than 7v,
So you might use the 5v to connect a arduino to a powerbank, usb cable

all these comments saying that with the same price they can buy 20 of them from china i would sugggest to remember that in the first place ruggeduino was created be implemented in industrial use and enviroment. if you put an arduino in an industrial situation it wont last longer. because arduino has no ESD protection no current limit protection no current limit on the pins no precision clock no protected and insulated pins no over voltages and no possibility to run from -40 to 85 degrees celsius. This is the difference not the fact that you coulf buy 10 from china at the same price, of course you could but it will last a week on an industrial enviroment and also is not even certified and protected so the price is fully justified
ruggeduino advertisement :-D
Not really. Nobody is more quickly irritated than I am by "click bait" that promises you something and then delivers junk. I agree that a couple of pitches are made for the ruggeduino, but the video is also full of very useful information for those who don't have a ruggeduino. I was glad I watched it.
i connected my arduino to my laptop adaptor (19V 3.42A ) i was shocked when i saw it was working
Don't use heavy hammer to tune quartz frequency. Small stone is okay. :D (sarcastic)
Good board but too expensive for consumers (target group??). I hope China will come with a copy soon, I dont like to pay for logo.
+Jeroen vd Velden You are not paying for a logo. You are paying to people which spend their time, money and afford on this project (arduino). Why people see only parts price? I'm working on many projects, at the end there is a hardware and software part. Manufacturing costs are few Pounds, but I wouldn't bothered to working on something for manufacturing price...
The arduino brand premium price is more of a donation than anything else.
+Jeroen vd Velden have a look at ebay, and use the site where the currency is low. I'll bet you'll find an original or a good copy from one of the arduinopartners for around 7 euro or less. Believe me, blowing up an arduino is not very hard to do :(
I nearly trashed my Arduino by unwittingly creating a short circuit...
can u the nest vid be on coding

It's the wrong channel for programming, I think.
It looks like it was sponsored wasn't it?
In short, learn what you're doing, check your connections twice, and never change your connections while the system is on.
I've repeatedly shorted my IO pins accidentally and nothing has happened yet.
that's interesting. I've got an italian uno. I'm pretty sure that I shorted an oscillating digi out to ground for a few seconds once and it survived, so I assumed that there was some sort of current limiting built in. Not sure.
are we going to talk about a miracle cure for an arduino that you accidentally fried? :( no? okay :(

For one ruggeduino you can buy 25 Arduino Uno clones from china. You can destroy 24 learn an awful lot and still have one that works. Why would i ever by an Arduino for $50?? This is a bad ad for an overpriced product.
exactly.
I've caused some serious damage to the ATMega328 on two of my UNO's from overvoltage. Don't accidentally loop 24v back to them, folks.
However I am certain I can fix them by just...replacing the ATMega328 with another one from eBay for less than dollar. The chip is designed to be easily removed and replaced.
That's how you learn electronics.
LsHallo Vader
Yep. I've actually replaced the aforementioned Unos with some 101s. The 32mhz is really noticeable with what I do with them, so I'll be more careful with these. I plan to repair the Unos and use them only for testing purposes.
Why?: It is a common misconception that the Arduino 5V regulator will ensure that the 5V voltage remains at 5V, no matter what. IT WILL NOT! The only thing the 5V regulator can do is control current coming from the USB port or the external DC power jack. If the current is coming from an external power source directly connected to the 5V connector pin, the regulator can do nothing about it.
Another consequence of applying more than 5V to the 5V connector pin is possible damage to the PC's USB port. If the Arduino is powered from USB then this excessive voltage can cause current to flow backwards through the voltage-switching MOSFET T1 and back to the PC's USB port.
