Reverse-engineering infrared protocols using the Arduino-IRremote library.

Build

Here’s a quick demo..

IR Receiver

I’m using a CHO 1838 - compatible with the TSOP1838

pin	function
1	data out
2	GND
3	VCC (5V)

Construction

Just need the IR receiver connected to the Arduino Uno..

Code

The Dumper.ino sketch is based on the ReceiveDump.cpp demo from the Arduino-IRremote library.

Point a remote control at the receiver and press a button. The full dump of the pack is echoed to the console:

Arduino-IRremote library supported protocols: Denon / Sharp, JVC, LG, NEC / Onkyo / Apple, Panasonic / Kaseikyo, RC5, RC6, Samsung, Sony, (Pronto), BoseWave, Lego, Whynter and optional MagiQuest.

About LEAP

LEAP is my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know or send a pull-request.

NOTE: For a while I included various scale modelling projects here too, but I've now split them off into a new repository: check out LittleModelArt if you are looking for these projects.
