A grove potentiometer unit quickly wired on your M5Stack project
This unit contains a 10 KOhms rotary pot. and can be used to give a reference voltage for volume controle, brightness or speed.
The potentiometer is a variable resistor which outputs a voltage between 0 and VCC depending on the position of the potentiometer.
The output voltage is captured by an analog input on the ESP32 (on port B) and converted the voltage to a numerical value with the Analog-to-Digital converter on the ESP32.
The unit interface is black to indicates that's a Grove B interface (ADC, DAC, GPIO).
- Output voltage range: 0 to 2.5V
