POLAR DIMMABLE LED PROJECT

The polar dimmable LED project is a prototype that shows the working principle of a dimmable lighting system in the room of a building, but this project comes with a twist.

In this project, when the brightness of one led (used to represent the lighting system) increases, the other decreases.

COMPONENTS USED:

• Two LEDs (Light Emitting Diodes).

• One Analogue Potentiometer.

• Arduino Uno R3 Board.

• Two 330-ohm (Ω) resistors.

• Jumper wires.

HOW IT WORKS:

The total resistance of an analog potentiometer is the addition of two resistors connected in series within it. As the knob is turned, the wiper of the knob moves from end of the potentiometer to another, that is, it moves from one resistor to another. The implication is the resistance of one resistor reduces while the other increases.

For this project, the components (the Arduino board, the potentiometer, and LEDs) have been programmed in such a way that as the knob is being turned and the resistance of one resistor decreases while the other increases, the brightness of one LED increases while that of the other (LED) decreases, and vice versa.

Below is the Tinkercad Simulation of the project;
