    Usage and assumptions:
    Based on TSOP 1738 IR device, Vcc to 5Volt, Gnd to Gnd, Out has pull-up of 10K
    to Vcc and Out has diode (Cathode to Out) connected to pin (p16) (Anode to p16)
    and pin (p16) has mode PullUp
    
    This will allow a "standard" RC5 device to be used to read it transmitted codes.
    Still work in progress (in due time) to add newer rc6 devices
