Arduino UNO. IR sensor. LED. Jumper Wires. Working Principle: IR Sensor Operation: The IR sensor emits infrared light from an LED and detects the reflected light with a photodiode. When an object ...

This project demonstrates how to use an IR sensor module with an LED controlled by an Arduino board. The IR sensor module is connected to pin 6 of the Arduino board, and an LED is connected to pin 5.

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.
