Potentiometer

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:

• 1 x Arduino Uno
• 1 x Breadboard
• 1 x LED
• 560 Ohm Resistor (Green-Blue-Brown)
• 1 x Potentiometer

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.
