=== decoding for LG A/C ====
- 1) remote of LG AC has two type of HDR mark/space, 8000/4000 and 3100/10000 
- 2) HDR 8000/4000 is decoded using decodeLG(IRrecvDumpV2) without problem
- 3) for HDR 3100/10000, use AnalysIR's code : http://www.analysir.com/blog/2014/03/19/air-conditioners-problems-recording-long-infrared-remote-control-signals-arduino/
- 4) for bin output based on AnalysIR's code : https://gist.github.com/chaeplin/a3a4b4b6b887c663bfe8
- 5) remove first two byte(11)
- 6) sample rawcode with bin output : https://gist.github.com/chaeplin/134d232e0b8cfb898860


=== *** ===
- 1) Sample raw code : https://gist.github.com/chaeplin/ab2a7ad1533c41260f0d
- 2) send raw code : https://gist.github.com/chaeplin/7c800d3166463bb51be4


=== *** ===
- (0) : Cooling or Heating
- (1) : fixed 
- (2) : fixed
- (3) : special(power, swing, air clean)
- (4) : change air flow, temperature, cooling(0)/heating(4)
- (5) : temperature ( 15 + (5) = )
- (6) : air flow
- (7) : crc ( 3 + 4 + 5 + 6 ) & B00001111


°F = °C × 1.8 + 32
°C = (°F − 32) / 1.8
