ESP32 Analog Input with Arduino IDE | Random Nerd Tutorials

The ESP32 DEVKIT V1 DOIT board (version with 30 pins) has 15 ADC pins you can use to read analog inputs. These pins have a resolution of 12 bits, which means you can get values from 0 to 4095. To read a value in the Arduino IDE, you simply use the analogRead() function. The ESP32 ADC pins don’t have a linear behavior. You’ll probably won’t be able to distinguish between 0 and , or ...
