In this tutorial, we will learn to use a potentiometer with Arduino. It allows us to change its value by turning a small knob, the analog value read by Arduino will enable us to do our flashing of the LED depending on the value read.
-Connect the LED as shown on the image.
-Connect to pin A0 the middle pin of the potentiometer
-Connect the other two leads- one to the GND and the other to the 5V pin. This does not affect the functioning of the potentiometer.
List of components:
|R1||1||220 Ω Resistor|
|Rpot1||1||10 kΩ, Potentiometer|
|U1||1||Arduino Uno R3|
