Universal IR Remote

A versatile infrared remote control built around the CH554 microcontroller, designed to learn and replicate IR signals from any infrared-controlled device.

Overview

This project implements a universal remote control capable of capturing, storing, and transmitting infrared signals from virtually any IR-based device. Whether you're controlling TVs, air conditioners, sound systems, or other IR-enabled appliances, this remote can learn and replay their commands.

Hardware

Microcontroller: CH554 (8051-core USB MCU)
IR Emitter: Infrared LED for signal transmission
IR Receiver: Infrared sensor module for learning mode
Power: USB-powered via CH554's built-in USB interface

Features

Learn IR signals from existing remotes
Store multiple device profiles
Transmit learned IR commands on demand
Supports various IR protocols (NEC, RC5, Sony, etc.)
USB connectivity for programming and power
Compact and portable design
