For example in this tutorial, we are using pin number 15 as a digital input, so we will use this function like this digitalRead(22) or we can define 22 with any name and use name instead of pin number as we did in the example code below: ...
it on the serial monitor of Arduino IDE. ESP32 analog channels are of 12 bit which means the minimum step of each voltage level is between0 and 4095. Analog channel produces a digital value between 0 and 4095 according to the voltage at the input of the analog channel. For example ...
