Components Description
- 1 X LED: We are controlling only one LED in this program.
- 1 X Resistor, 330 Ohm: For every LED, we need one current limiting resistor.
- Breadboard: A breadboard is a fundamental tool used in electronics and prototyping to build and test circuits without soldering.
- Arduino UNO R4 or earlier versions.
- Jumper wires: Jumper wires are simple electrical wires with connectors on both ends used to create connections between various electronic components or points on a circuit on a breadboard.
- Potentiometer: A potentiometer, sometimes known as a “pot,” is an electrical component used to manually change the resistance in a circuit.
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.
