Tutorial: How to Use 2-Piece MF-A02 Knob

The 2-piece MF-A02 knob is ideal for controlling human-computer interfaces in human-robotic interface projects. Suitable for beginners and intermediate users.

What you need

• 2-Piece MF-A02 Knob
• Arduino
• USB cable
• 10kΩ resistor

Steps

1. 1. Check the datasheet for the knob specifications.
2. 2. Connect the potentiometer to pin A0 on the Arduino.
3. 3. Connect the 10kΩ resistor between VCC and GND on the Arduino.
4. 4. Download the provided Arduino code.
5. 5. Upload the code to the Arduino.
6. 6. Check the potentiometer movement with the onboard LED.
7. 7. Adapt the code to control other components.
8. 8. Test the potentiometer in various projects.

Example code

```
void setup() {
  pinMode(A0, INPUT);
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  int val = analogRead(A0);
  digitalWrite(LED_BUILTIN, val > 512);
}
```

Mini project

Create a remote control for a drone using two MF-A02 potentiometers and a stepper motor.

Common mistakes

• Connect the potentiometer to a digital pin instead of an analog one.
• Omit the pull-up resistor.
• Forget to upload the code to the Arduino.
• Do not check the connections before running the code.

Recommended accessories

• Stepper motor
• PWM control
• Arduino Nano
• Short USB cable

Frequently asked questions
