• CARRIER
  • Frequency = 40 KHz
  • Duty = 1/3

• ZERO
  • CARRIER for 0.5ms
  • LOW for 0.5ms

• ONE
  • CARRIER for 0.5ms
  • LOW for 1ms

• FRAME (total 60ms):
  • 8ms Carrier = preamble
  • 4ms LOW
  • 8 BITS address, LSB first, duration depends on 0s,1s in the byte
  • 0.5ms CARRIER = END (of byte)
  • 4ms LOW
  • 8 BITS command, LSB first, duration depends on 0s,1s in the byte
  • 0.5ms CARRIER = END (of byte)
  • LOW until 60ms FRAME duration

• A Multi-Protocol Infrared Remote Library for the Arduino

Do you want to control your Arduino with an IR remote? Do you want to use your Arduino to control your stereo or other devices? 
This IR remote library lets you both send and receive IR remote codes in multiple protocols. 
It supports NEC, Sony SIRC, Philips RC5, Philips RC6, and raw protocols. 
If you want additional protocols, they are straightforward to add. 
The library can even be used to record codes from your remote and re-transmit them, as a minimal universal remote.
