ESP32: Analog values measure at the input
18.06.2021 237
The ESP32 has two analog digital converters and can thus read values in parallel on most GPIO pins A voltage of 0 to 3 3 volts can be applied to each input PIN or measured The values are read as integers from 0 to 4095 with the analogRead(PIN) command The analog in
