jheronymus / raw-ir-decoder-for-arduino

Take raw IR signal from a remote receiver and print out pulse lengths

IR decoder

Decodes long IR codes, for example from air conditioner / heat pump devices.

Shows the timings, the symbols, and also the decoded signal for certain air conditioners.

Instructions

• Connect an IR receiver into the Arduino

• Start the sketch, and enter 1, 2 or 3 into the 'Serial Monitor', to select which timings to use

  • Try out the alternatives until you get sensible output
  • The signal should always start with 'Hh', and within the signal there should only be a couple of 'Hh' pairs (if any)
  • 'H' and 'h' should be there only in pairs 'Hh'
  • 'H' stands for 'header mark' and 'h' for 'header space'

• Point your IR remote to the IR receiver and send the code

• Mode '9' can be used to decode known signals, in that case you can send the symbols from the terminal, like entering this:
