This circuit is based on ARDX 8 which uses a potentiometer to change the flash rate of an LED. Start by gathering your parts together:
Step 1 – Build your circuit
Step 2 – Write your code
Upload and run your code.
Step 3: Extensions
- Use if statements to create upper and lower limits.
- Swap the LED for a Servo.
- Add multiple LEDs so it switches from one LED to another as your turn the potentiometer.
