Arduino Example

Arduino Potentiometer Example

Read analog value from a potentiometer.

Wiring

Check pinout, power supply, common GND and voltage levels before connecting the module.

Full code

const int potPin = A0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.println(analogRead(potPin));
  delay(200);
}

How it works

This lesson matches the page title and gives a clean starting point for this exact example.

Common mistakes

Check board selection, wiring, libraries, power supply and serial monitor baud rate.
