Linear/Slide Potentiometer Module

Introduction

The slide potentiometer is a linear variable resistor with a total resistance of 10k. When you move the lever from one side to the other, its output voltage will range from 0 V to the VCC you apply. It has four pins, 3 of which are connected to VCC, GND and the ADC IN on the slide, while the remaining pin is connected to a red indicator LED. You can use the indicator LED to visually display the change on the potentiometer.

Application Ideas

<syntaxhighlight lang="c">

int adcPin = A0; // select the input pin for the potentiometer int ledPin = A1; // 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("Sliding 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);
