#624 IR Dumper

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


Here’s a quick demo..




IR Receiver

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

pin function
1 data out
3 VCC (5V)


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




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.

LEAP is just my personal collection of 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 (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:
