What you need

• 2 Potentiometers handle B50K
• Arduino
• Power cable
• Multimeter (optional)

Steps

1. 1. Check the datasheet for the specifications of the potentiometer.
2. 2. Connect a potentiometer to pin A0 of Arduino.
3. 3. Connect the GND pin of the potentiometer to the GND of Arduino.
4. 4. Connect the VCC pin of the potentiometer to the 5V of Arduino.
5. 5. Upload the following code to Arduino.
6. 6. Adapt the code to the pin number used.
7. 7. Try turning the knob and observe the values.
8. 8. Repeat for the other potentiometer.

Example code

```void setup() {} void loop() { int val = analogRead(A0); Serial.println(val); }```

Mini project

Create a volume control for a virtual amplifier using a potentiometer.

Common mistakes

• Connect VCC correctly to 5V and GND to GND.
• Check the datasheet to see if the potentiometer supports direct connection to Arduino.
• Ensure that the potentiometer is properly connected to avoid intermittent connections.
• Check that pin A0 is correctly used in the code.

Recommended accessories
