Infrared -> RS 232

  1. Sep 29, 2007 #1
    does anyone know how what type of circuit i need to transmit a signal over InfraRed. the signal i want to transmit is for example one byte -> 1010 1010

    the byte sent will be sent to a RS 232 port

    i have a shift register with the data ready to be sent

    i know that i need a IR photodiode and a phototransistor

    :. sorry double posting

    Before anyone gives Tko grief about double-posting, it was my suggestion that (s)he resubmit this here after I ran across it in General Physics. This seems to be a more appropriate location.
