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 ...
I'm using a DFRobot ESP32-C3 and want to monitor it's battery voltage using ADC1 GPIO 2. The circuit for connecting up GPIO2 is a voltage divider and a capacitor. I've verified the resistor values with a multimeter and tested for continuity. The problem is that despite the supply ...

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 have also attached the PDF schematic so that you can look at that. This is also what i am using to upload the code in arduino ide. Any help would be amazing. Thanks.You do not have the required permissions to view the files attached to this post.Last edited by MrT Stephens on ...
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 see all the .ino tabs upon opening the Arduino IDE, that means you have opened the code properly. I used the Arduino tab feature to subdivide thousands of code lines for organization. You can click on the tabs to view the different sections of the firmware. You can leave all the...
