Ir remote control
Decoding your remote control

/*
* IRhashdecode - decode an arbitrary IR code.
* Instead of decoding using a standard encoding scheme
* (e.g. Sony, NEC, RC5), the code is hashed to a 32-bit value.
*
* An IR detector/demodulator must be connected to the input RECV_PIN.
* This uses the IRremote library: http://arcfn.com/2009/08/multi-protocol-infrared-remote-library.html
*
* The algorithm: look at the sequence of MARK signals, and see if each one
* is shorter (0), the same length (1), or longer (2) than the previous.
* Do the same with the SPACE signals. Hszh the resulting sequence of 0's,
* 1's, and 2's to a 32-bit value. This will give a unique value for each
* different code (probably), for most code systems.
*
* You're better off using real decoding than this technique, but this is
* useful if you don't have a decoding algorithm.
