Shows how to use Touch Pad for ESP32 and ESP32-S2. A Touch Pad is a pin that is sensitive to touch. It can be just a wire, a surface made out of various materials.
The sample is located here.
Either an ESP32 or an ESP32-S2. Other series do not support Touch Pad.
The sample contains different functions that you can call to understand how things work. The code is commented.
Important: some elements are ESP32 specific and some other S2 specific. Be careful when using those.
