The analog value on the Arduino analog pin A0 is changed using a potentiometer. The value read on this pin by the Arduino is used to change the rate at which the on-board LED flashes.
1 × 10k potentiometer
File → Examples → 3.Analog → AnalogInput
Connect the potentiometer as shown on the Arduino website AnalogInput page.
Open the sketch in the Arduino IDE (File → Examples → 3.Analog → AnalogInput) and then upload it to the Arduino board.
As the shaft of the potentiometer is rotated, the rate at which the Arduino on board "L" LED flashes will change.
