Introduction
This microcontroller project demonstrates how to capture and analyze raw infrared (IR) data from a Keyes IR remote using the NEC protocol. Built around an Arduino Uno, the project focuses on decoding IR signals and displaying detailed timing and protocol information via serial output.
It is especially useful for learners exploring Proteus simulation, embedded systems, and practical electronics related to remote control decoding.
The project helps understand how consumer IR remotes communicate at the signal level.
It is a solid foundation for building IR-based control systems.
This setup is fully suitable for simulation and real hardware testing.
This Arduino IR Proteus Simulation helps beginners understand infrared signal decoding, NEC protocol timing, and embedded systems behavior using virtual hardware.
How the Project Works (Overview)
An IR receiver module connected to the Arduino captures infrared pulses transmitted by a Keyes remote.
The IRremote library decodes these pulses and identifies the protocol type (such as NEC).
Once a button is pressed on the remote, the Arduino processes the signal and outputs:
-
Encoding type
-
Hexadecimal command value
-
Bit length
-
Raw timing data
All decoded information is sent to the serial monitor for analysis.

Explanation of the Code (High-Level)
The code initializes the IRremote library and assigns pin D11 as the IR receiver input.
When a signal is detected:
-
The decoding type (NEC, SONY, RC5, etc.) is identified
-
The hexadecimal value and bit count are printed
-
Raw timing values are displayed in microseconds
-
Source-ready raw arrays are generated for reuse
This modular structure makes the firmware easy to extend or modify.

}Proteus Simulation
In Proteus, the Arduino Uno is connected to an IR receiver module at pin D11.
When IR signals are injected (or simulated), decoded data appears on the virtual serial terminal.
This allows testing protocol decoding without physical hardware, making it ideal for VSM-based learning.The Arduino IR Proteus Simulation accurately displays decoded IR data on the virtual serial terminal when a Keyes remote button is pressed.
