Welcome to Potentiometer Module repository
Introduction of Potentiometer module
1. Working principle
The potentiometer (adjustable resistor), it has three terminals, and its resistance can be adjusted according to a certain change rule.
Potentiometers are usually made up of resistors and rotating or sliding systems. This potentiometer, the analog value of the OUT pin output is 0~1023.
2. Practical application
2.1 As a voltage divider.
2.2 As a varistor.
2.3 Adjust the brightness of the light, adjust the knob to control the brightness of the RGB light.
3. About module
3.1 Potentiometer module possess 4 Alligator clip port, Corresponding to GND, VCC, NC and OUT. The OUT pin is the signal output pin of the button module.
3.2 4 pin female socket.
3.3 PH2.0 cable interface.
Adjustable knob, rotate clockwise, the smaller the value of OUT output, rotate counterclockwise, the larger the value of OUT output.
Working Voltage: 3.3V/5V
