Can you help with the modification of the pipan.php script in Silvan Melchior's excellent RPi_Cam_Web_Interface to drive this board on Arduino i2c !! It will help me and many others.

What kind of library is it that? , can't open file

No body knows the 12v or 24v positive and negative conditions which is which

Thank you!!!

cant get it to work here is error messages: Arduino: 1.8.18 (Windows 10), Board: "ESP32 Wrover Module, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), QIO, 80MHz, 921600, None, Disabled" C:\Users\owner\Documents\Arduino\libraries\ESP32-Arduino-Servo-Library-master\src\Servo_ESP32.cpp: In member function 'bool Servo_ESP32::attach(int, int, int, int, int, int)': C:\Users\owner\Documents\Arduino\libraries\ESP32-Arduino-Servo-Library-master\src\Servo_ESP32.cpp:66:5: error: 'ledcSetup' was not declared in this scope 66 | ledcSetup(_channel, 50, 16); // channel X, 50 Hz, 16-bit depth | ^~~~~~~~~ C:\Users\owner\Documents\Arduino\libraries\ESP32-Arduino-Servo-Library-master\src\Servo_ESP32.cpp:67:5: error: 'ledcAttachPin' was not declared in this scope; did you mean 'ledcAttach'? 67 | ledcAttachPin(_pin, _channel); | ^~~~~~~~~~~~~ | ledcAttach C:\Users\owner\Documents\Arduino\libraries\ESP32-Arduino-Servo-Library-master\src\Servo_ESP32.cpp: In member function 'bool Servo_ESP32::detach()': C:\Users\owner\Documents\Arduino\libraries\ESP32-Arduino-Servo-Library-master\src\Servo_ESP32.cpp:80:5: error: 'ledcDetachPin' was not declared in this scope; did you mean 'ledcDetach'? 80 | ledcDetachPin(_pin); | ^~~~~~~~~~~~~ | ledcDetach exit status 1 Error compiling for board ESP32 Wrover Module.

hi bro. 200 amps continues load capable? . leads looks so small.what is the resistance of the current leads.

Cannot understand a word.

Please keep the metalic ruler away from your electronics. If by any chance it touches your vcc gnd pins together, you what happens!!

Step up or step down ؟؟؟؟

I need exactly the same set up including 16 on and off toggle switch with 16 relay.

Ahmed, thank you for this CZcams content. It is very useful. My ESP32 is working, but is crazy slow. It takes about 3 seconds to take a still picture, and videos are almost impossible (even at 240x240). Is there a way to boost the memory in the "Huge App" partition? It looks like it has 3MB for the app, but the board I bought on Amazon has 8MB. I bought: Aideepen ESP32-CAM W-BT Board ESP32-CAM-MB Micro USB to Serial Port CH-340G with OV2640 2MP Camera Module Dual Mode support NodeMCU.

i see your still making youtube videos so i thought i might have a shot getting some help on this could you possibly do a video on this and show how to make it so it rotates 180° every time it’s powered?

Actuallyis way more easy to assemble the case starting from the top layer from the bottom. fit the four long screws, then assemble the three layers install buttons and secure them with screws. Then install the oscilloscope main board, fit it in the display connector. Then using the last four nuts, fix the main board to be parallel with the top layers. Last come the bottom cover. with those special nuts.That's it

hi, i might need your help, i reset my devo 10 transmitter and apparently i cant do gps hold for my waalkera furios 320 drone. any advice for the setting?

That was a perfect demo of the sensor, thank you.

just to clarify, powering a electrical component with 5v will make its logic at 5v. if your lcd is 5v powered and since the esp32 logic is 3.3v that means the sda and scl pins and all gpio pins on the esp32 can only handle 3.3v and CANNOT handle 5v you can degrade your esp32 this way or even fry it or damage it. consider using a logic level shifter (compatible with i2c) with the i2c pins from the lcd to the esp32.

Can i use 36v battery and 36v dc supply with this module?

4th grader school project

Hello, what module do you recommend the one that appears in the video or this W XL4016 DC-DC Max 9A, for a 90W 19V 4.5A source?

If you put a smal cpu fan that would help with power increase?

I just got mine in the mail and used an 18 volt battery stepped down to 12.8 volts at 5 amps and i can't get more than 1.6 amps. So its not 300 watt but more like 20 watt! Oh well time to modify! Cheers from Australia subbed and liked 👍

Can you show me with ESP32 please

It is showing 1 volt difference from battery what to do how can set its voltage equal to battery voltage??!

first time using xt60 connectors, didn't realize male and female are counterintuitive D: kind of figured out the third hand and the solder flux tips on my own, but now have to redo it agian, thanks for great instructions!

Can I control the module from Iphone ? which app to use for iphone?

Tyvm very helpful video. Had to add my grandpa's second cell number. His first one isn't working well (he has old flip phones) so ty for making this easy to follow video.

Did a similar things in combination with a water sensor to pump out condenswater from the hvac system. Instead of the driver i used a relay to which you can attach stronger pumps if needed. The shown one will break if you use it without water or the inside will just rust away. Do you also have examples with relays?

Thank you, brother, be blessed!

Thank you, i indicate sensitive of touching with cable and i detected there is something relate of resistivity, finally i found the solution.

Your transmitter (remote) can work automatically to on/off submersible pump motor, For auto run when water tank 50% empty and automatic stop when full tank???

Perfect! 👍👍👍

this works perfectly, thank youu!!

Very useful video sir

Newbie here. Why use a 10 kohm resistor? What chip does the amplifier use?

Can anyone help me wire this thing? I have a 110v controller sending out one black and one red 12v line to motor. Two wires that’s it. I want to make a 12v mixer motor go back and forth in different directions 2 seconds in each direction on its own. I have a polarity changing switch that works great but I have to flip it manually. I’m just looking to be able to walk away from the unit and have it go clockwise/counterclockwise continuously on it own

thanks mr

Great video, I want to delay the relay to trigger after receiving a signal but stay triggered until signal disappears, Can this be done?

Thank you so much for this video, and the derailed breakdown of this device. It really helped me out on having to figure out which wire goes where.

Good review! I only wish that every ebay/aliexpress circuit had something similar

new update from my last common .i change the fuse from 20A to 40A . and last test update is input 11.85V(dropped limited input) with 27A (320W) and get output 56V 3.85A (216W) efficiency 68% with that range between 12v and 56V .... and i stopped the test . because the coil and mosfet get crazy over hot in 26A input for 2min ( need more big cooling )….. i think after i modified the component in the board it worked very very very good. ( if any one need feedback on this model please be free to pin to me about it . this model it have more power than you think but not from the company because they have too many things need change maybe for bad calculation design or bad component power .
