Keyestudio EASY plug Analog Rotation Sensor


The sensor is based on a potentiometer. A potentiometer is also known as a variable resistor. It is a perfect demonstration of a variable voltage divider circuit. Its voltage can be subdivided into 1023, easy to be connected to Arduino with our sensor shield.
Combined with other sensors, you are able to make interesting projects by reading the analog value from the IO port.
Note: this module should be used together with EASY plug control board.


  • Connector: Easy plug
  • Supply Voltage: 3.3V to 5V
  • Sensor type: Analog

Technical Details

  • Dimensions: 39mm*20mm*29mm
  • Weight: 9.1g

Connect It Up

Connect the EASY Plug potentiometer sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Copy and paste below code to Arduino IDE and upload.

void setup()
Serial.begin(9600); //Set serial baud rate to 9600 bps
void loop()
int val;
val=analogRead(3);//Read rotation sensor value from analog 3
Serial.println(val,DEC);//Print the value to serial port

What You Should See

After uploading the code, open the serial monitor and set the baud rate to 9600, you should see the analog value showed on the monitor. If rotate the potentiometer, the value will change within the range of 0-1023.
