In summary, in this article, you learned how to use the LED PWM controller of the ESP32 with the Arduino IDE to dim an LED. The concepts learned can be used to control other outputs with PWM by setting the right properties to the signal. We have more ESP32 resources you may like: G...
You can wake up the ESP32 from deep sleep using the touch pins. This section shows how to do that using the Arduino IDE.Enable Touch Wake-UpEnabling the ESP32 to wake up using a touchpin is simple. In the Arduino IDE, you need to use the following function—pass as argument the ...

Lesson for me is to exercise more caution over using the strapping pins (2,8,9) and to go back to the schematic. This is only the second board I've used so lots to learn.scuba-hacker Posts: 3 Joined: Sun Dec 17, 2023 11:06 pm Re: ESP32-C3 ADC odd behaviour by scuba-hacker...
IDE. Its "call to fame" is that it makes it easy for anyone that is familiar with the Arduino to leverage their knowledge and create gadgets that need more memory and processing power than what the Arduino Uno can provide, in addition to Wifi and Bluetooth. All this at a lower price ...

I tryed to design ESP-WROOM-32 (just pure module, not dev. board) myself. I am using UART and boot mode to upload Arduino code into ESP32. The problem start when I tryed to add MCP3221 (12bit I2C AD Converter). I used pins 21 (GPIO7) and 22 (GPIO8). But than I can not...
It seem the ESP32 don't start ! I swapped one of the ESP32 with a brand new one and the problem still persist, i think there is a design problem with my PCB but i don't know where Here the design schematic.png Does anyone already have the same problem ? Thanks a lot JulienYou...
If you fail to do this, the Arduino sketch/ firmware would not open properly. Click on any of the sketches with the properly labeled folder to open the program. If you see all the .ino tabs upon opening the Arduino IDE, that means you have opened the code properly. I used the ...
