Hello, At first thanks for informations, just i want to ask why we use R 1K to reset pin?

No longer works. Adafruit made changes to the library.

video evidence on why most models on thingverse suck. how id you put so much effort into documenting your laziness? Uploaded knowing it was a failed design, because "he had to many hours in the design and was ready to print something." Don't worry someone remixed the cap and fixed it after several people wasted their time and filament.

I typed this in my search, couldn’t find this video, then wait two days and it’s on my recommended, if anyone else is wondering what’s going on with google ad and search engine ai let me know cause this is nuts…. Anyways, thanks so much for this video!

Hello sir. I have a problem with MCP3008 sampling frequency. I am trying to increase clock speed for better sampling rate but it does not work. Is there any way for this or any suggestion? And also I tried software SPI configuration, it gives an error does not work either. Thanks for your explanation.

Working on putting together a fully automated brewery using craftbeerpi. Just need to figure out how to incorporate it with the automation of the software. Thanks for the great tutorial.

Hey so I have a hi wonder jet max robot arm that uses servos. When I connect one of the servos it crashes the raspberry pi. Any ideas why this may be happening?

Thanks a lot! 感谢！思路，讲解清晰，听明白了。

What about esp32 running micropython? Thanks.

I have a problem, can anybody help me ? I have a mcp2307 and raspberry pi4 which is commmunicate with i2c protocol. When I set logic high one mcp pin all pin goes high. Have you any idea on this issue?

Are you stupid? There is a 13% difference in humidity! How can you act like everything is working OK?

I think I have fake ebay MCP's , that's the second tutorial I follow that does not work, Already bought MCP from Mouser :(

You need activated carbon to remove smoke properly

Why are you doing it in Python?

The code is full of syntax errors. I worked through them and got it to work though.

He never said what resistor to use with the LED. Anyone have an answer to this? Thank You.

I wouldn't recommend hooking up with power applied. Connect, check, then apply power.

Have you measured how many microseconds it takes for digitalRead() and digitalWrite() using these 16 GPIO pins via I2C compard to the pins which come on the microcontroller? Just wondering how much slower it is. Hopefully it doesn't take more than say 100 microseconds.

you made my day

Hi could you do video arduino and raspberry pi zero w and flysky controller to help stop biter

Working on a 16 step switch project. Each key has an embedded led. For 16 switches I actually need 32 gpio. Your video helped me to figure out how to work with this chip properly with a Pi Pico. Very helpful video! Thank you.

Did you really upload a 9 minute video of how to duct tape a furnace filter to a box fan?

Greetings human! Just wanted to stop by and thank you for taking the time to enter the Maker Contest. That collective looks really solid, even for a prototype.Found the other video that shows it in action,"DIY Arduino Helicopter Collective Joystick Control"... "autohover?" SOOO cool! Be well and happy Making! -Volt (Chris and Ray)

Nice submission. Do you have video of the thing controlling the simulator?

In short and simple... nothing better than this video... Great Video.... 😀

thanks dude!!!, you saved my life, get my like

nossa! muito bom esse estojo, já estou imprimindo o meu também

this thing is awesome, I'm rooting for ya!

Can you help please ..proteus not able to locate Adafruit_MCP23X17.h .. i tried everything but still not working .. below the error msg ... make[1]: Leaving directory `C:/Users/kail/AppData/Local/Temp/VSM Studio/10d5e1155d14460db955271ef37a960a/ARDUINO UNO_1/Debug' In file included from C:/Users/kail/Documents/Arduino/libraries/Adafruit_MCP23017_Arduino_Library/src/Adafruit_MCP23X08.h:8:0, from C:/Users/kail/Documents/Arduino/libraries/Adafruit_MCP23017_Arduino_Library/src/Adafruit_MCP23X08.cpp:5: C:/Users/kail/Documents/Arduino/libraries/Adafruit_MCP23017_Arduino_Library/src/Adafruit_MCP23XXX.h:8:37: fatal error: Adafruit_BusIO_Register.h: No such file or directory #include <Adafruit_BusIO_Register.h> ^ compilation terminated. make[1]: *** [arduino/Adafruit MCP23017 Arduino Library/Adafruit_MCP23X08.cpp.o] Error 1 make: *** [main.cpp] Error 2

Will the filtered smoke still generate heat?

I am using the Adafruit librabry and got my Python running. Is there a way to initiate the mcp() so that when I read the pins it says 1/0 not True/False?

Typo in the title :)

This is a cool project with all sorts of things mixed together, with 3D printing, electronics and overall fun stuff... But.. what happened? You disappeared!? 😥

I’m using your code in thonny on my pi and it doesn’t seem to work it keeps saying that it cannot find the Adafruit GPIO and I know I installed it do you have any idea what I’m doing wrong

Fraction one please 29pc

Do a fraction 29 pc one please

I'm very very new to this but can someone broadly explain the difference between this and a shift register?

not working. double checked. all ... fixed for python3 .. nothing. thanks anyway.

hi is it possible to have the Arduino and Raspberry Pi connected to the same ic2 line at the same time?

When I cook a steak on my induction hot plate it creates a load of smoke. Will this work to stop the smoke in the air setting off my alarm and choking up the air in my apartment? Thanks.

Sorry for comment, but do not teach new people to wire things up with power applied.

Tip: Check the Red & Blue lines on the power rails for any breaks that indicate power termination. Nice video, subbed :D

Great video, Can we use K type thermocouple as the analog input instead of potentiometer? I have to interface thermocouple and raspberry pi?

Wat if the power cuts... Can we save the status of th pins of MCP23017 in the eeprom of arduino so that it regains its last state before the power cut

This is soo helpful, I couldn't find any proper explanation anywhere else Helped me for my project

There is a model of this board on GrabCad for those modeling their projects: grabcad.com/library/sparkfun-motor-driver-dual-tb6612fng-1a-1

Very helpful. I’m attempting to revive the old diamond rio MP3 player parallel interface so I can get some new music on my 23 year old MP3 player :)

The link of github seems broken.Can you upgrade it ? Thanks ! I really liked it.

Hello, can you please elaborate on why you use this "pull-up resistor"? I don't understand what it is for, as it seems to bypass the sensor? Thank you in advance. I just found your channel and it will help me a lot in my current project.

I'm running into the issue where the script is pushing the same temp, humidity over and over again - but when I cut, and rerun python file.py then it'll update the values, anyone know why this might be?
