Introduction
This project demonstrates how to send and receive infrared (IR) signals using an Arduino Uno inside a full Proteus VSM simulation. It’s a practical embedded systems project that helps students and hobbyists understand how IR communication works in devices like TV remotes, automation gadgets, and wireless control modules.This project demonstrates Arduino IR Communication Proteus simulation using two Arduino Uno boards. With Arduino IR Communication Proteus, an IR LED transmits modulated signals to a TSOP receiver, allowing protocol decoding using the IRremote library inside Proteus VSM.
The setup uses an IR demodulator to receive signals and the popular IRremote library to decode and display protocol information on the Serial Monitor. This makes it a great microcontroller project, especially for learning DIY electronics, Proteus simulation, and embedded system design.
How the Project Works (Overview)
The system consists of an IR transmitter and an IR receiver, each connected to separate Arduino Uno boards inside Proteus.
Here’s the basic idea:
-
An IR LED on the transmitter side emits infrared pulses.
-
The TSOP-style IR demodulator on the receiver side detects these pulses.
-
The demodulator outputs a digital IR signal to Arduino pin 11.
-
The IRremote library decodes the signal and identifies the protocol (NEC, Sony, RC5, etc.).
-
The decoded information is shown on the Serial Terminal inside Proteus.
The simulation provides a safe, hardware-free way to observe IR waveforms, debug timing values, and analyze how IR remotes communicate.

Explanation of the Code (High-Level)
1. Initialization
The receiver pin is set to digital pin 11, compatible with IRremote.irrecv.enableIRIn() activates the internal IR state machine.
2. Decoding IR Packets
Whenever an IR signal is received:
-
The library identifies the protocol (NEC, Sony, RC6, Panasonic, etc.)
-
Extracts the value, address, and bit length
3. Printing the Result
Three types of outputs are displayed:
-
Human-readable info (protocol + value + bits)
-
Raw timing data (useful for waveform analysis)
- C-style array output for replaying the code later
4. Resume Waiting
irrecv.resume() resets the decoder to detect the next IR command.
This makes it perfect for analyzing remote controls or creating your own universal IR transmitter.
