  IR decoding

  This is for the NEC codes that the IRRemote transmits.
  The Arduino Library has coding/timing for the other brands.
  The use of Interrupt timing was garnered/modified from the
  Arduino code
  .
  I used the falling edge of the signal from the detector
  to create an Interrupt.  The ISR (Interrupt Service Routine)
  grabs the system time [in millisecs - ms] and puts it in
  an array.  - just falling edges.
  '
  Then the array is scanned from the end to the beginning,
  {so the math is easier - for me} to get the time differences
  between the ending/falling edge of the pulses of the IR coding sequence that NEC uses.  I then manually decoded
  the 0's and 1's - oh, watch out that NEC transmits the LSB first and the final is the MSB {another reason to start
  from the end of the timing array- imo}

  Glitches

  I added another cap (capacitor)to the 5v line, - the servo motor induced a lot of false signals

  to the IR decoder chip.  I also put a .01 (?) cap on the decoder PCB also.  This reduces

  most of the interference.

  In the picture you may have noticed an object on top of the microcontroller.
  

  That is a 6 pin header soldered to the long leads of the cap, then inserted the leads

  into the PCB power connector - I ran out of places to put the (proto)  jumper cables/wires.
