[Arduino] Using an Infrared IR Remote Control

The infrared IR remote module is a low-cost module that works with the Arduino to send and receive data via infrared signals. It is used by connecting the VCC, GND, and signal pins to the Arduino and coded using the IRremote library. It sends data via infrared light, and the receiver detects the signal and passes it to the Arduino for processing. You can do a simple test to make sure your setup is correct.
