Introduction: IR Remote Analyzer / Receiver With Arduino
This analyzer receives 40 different IR protocols concurrently and shows the address and code of the received signal.
If you want to analyze your remote or want to control your Arduino application with a spare remote, you need to know the code sent for each key.
A serial or paralell LCD can be attached to operate this as a standalone device without the need of a Serial Monitor.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: BOM
- Arduino Nano or UNO
Serial 1604 LCD
Step 2: Software Installation
After installing the IDE and choosing the right board, open the Library Manager with Ctrl+Shift+I and search for IRMP. Install it and then choose File -> Examples -> Examples from Custom Libraries -> AllProtocols.
Enable the type of LCD you have at line 43 ff. All outputs can be seen also at the Arduino Serial Monitor, so there is no need to attach a LCD for analyzing!
Step 3: Analyzing / Receiving
Run the program and if an IR signal is detected, the built in LED will flash.
If the signal can be decoded the result is printed to Serial output (and the LCD). The trailing R means that this command is a repeat command.
If you need to analyze one of the 10 disabled protocols use the OneProtocol example.
