Rotary Potentiometer Module

Introduction

The Linker Rotary Potentiometer Module produces analog output between 0 and Vcc (5V DC with Arduino) on its D1 connector. The D2 connector is not used. The angular range is 300 degrees with a linear change in value. The resistance value is 10kΩ, perfect for Arduino use.

Application Ideas

test <syntaxhighlight lang="c"> int adcPin = A0; // select the input pin for the potentiometer int ledPin = 5; // select the pin for the LED int adcIn = 0; // variable to store the value coming from the sensor

void setup() {

 Serial.begin(9600);        // init serial to 9600b/s
 pinMode(ledPin, OUTPUT);    // set ledPin to OUTPUT
 Serial.println("Rotary Potentiometer Test Code!!");

}

void loop() {

 // read the value from the sensor:
 adcIn = analogRead(adcPin);
 if(adcIn >= 500)  digitalWrite(ledPin,HIGH);  // if adc in > 500, led light
 else digitalWrite(ledPin, LOW);
 Serial.println(adcIn);
 delay(100);
