The project is about how to use a IR receiver with a remote. By the end you will be able to print out the figures you press on the remote on the Serial monitor. I made this project so people can learn how to use a IR receiver and a remote. This work because as you press a button on a remote the receiver will read it and you can also just convert it to a hexadecimal so it is easier to read the values you get then makes two LEDs turn on or off

EXPANDED TECHNICAL DETAILS

Universal Protocol Decoding

This foundational project explores the world of Infrared (IR) communication used by millions of consumer electronics devices.

  • NEC/Sony/RC5 Protocol Support: Uses the IRremote library to capture 38kHz pulses. The Arduino decodes the specific 32-bit hexadecimal codes.
  • Learning Mode Logic: Includes a "Raw Data" mode where the user can point ANY remote (TV, AC, DVD) at the sensor and see the raw timing of the pulses in the Serial Monitor, providing a deep dive into pulse-coded modulation.

Control Implementation

  • Hardware Trigger Mapping: Includes a switch-case logic where specific codes trigger local hardware events, such as toggling a relay or changing the color of an RGB LED strip.
