What you need

• Arduino Uno
• Connecting wire
• Resistor sequence
• Multimeter

Steps

1. Connect the potentiometer to the circuit using connecting wires.
2. Check the resistance between the central terminal and one lateral terminal using a multimeter.
3. Connect the potentiometer pins to the microcontroller (GND, VCC, A0).
4. Write an Arduino sketch to read the potentiometer value.
5. Adjust the potentiometer and observe how the displayed value changes.
6. Check the datasheet for further information on technical specifications.

Example code

int potPin = A0;
int potVal;

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

void loop() {
  potVal = analogRead(potPin);
  Serial.println(potVal);
}

Mini project

Create a dimmer for an LED using the potentiometer to adjust the brightness.

Common mistakes

• Connect the potentiometer to the circuit without first checking the resistance.
