LED Control with Potentiometer using Arduino
In the field of electronics and programming, controlling an LED with a potentiometer is important too. By varying the resistance of the potentiometer, you can change the brightness of the LED. We will interface an LED (light-emitting diode) to the Arduino UNO board. An LED is a simple diode that emits light with a forward bias. We control the brightness of an LED by interfacing a potentiometer with it. We write a program in the Arduino IDE and download it to the microcontroller board.
