Linear Potentiometer (3-pin)

Pinout — Linear Potentiometer (3-pin)

Wiring notes

3-pin through-hole pot. Use componentId potentiometer-linear and put the **total resistance** in the label (e.g. "10kΩ", "100kΩ"). Standard pin names in diagrams: **CCW** (counter-clockwise end of track), **WIPER** (middle / slider), **CW** (clockwise end). Connect CCW↔CW across reference and GND (or signal range), take output from WIPER. Do not exceed pot power rating; as a voltage divider from 5V, current through the track is V/R_total.

This example was written and compile-checked for the arduino-uno. Codey Online adapts it to any other supported board for you.

// Linear Potentiometer (3-pin) example
// Reads the pot on A0 and prints the raw ADC value and voltage.

const int potPin = A0;
const float vRef = 5.0;

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

void loop() {
  int sensorValue = analogRead(potPin);
  float voltage = sensorValue * (vRef / 1023.0);

  Serial.print("ADC: ");
  Serial.print(sensorValue);
  Serial.print("  Voltage: ");
  Serial.print(voltage, 2);
  Serial.println(" V");

  delay(200);
}
