  1. other then a JK flip / flop (data-latch) what other methods of latching could be used to toggle a remote receiver connected to a relay between an on and off state. mcole

    latching

    other then a JK flip / flop (data-latch) what other methods of latching could be used to toggle a remote receiver relay between an on and off state. mcole
  3. thanks, but how does a Phototransistor work, what is the typical method of converting the output in to a useable signal for activation of say a relay, How is rectified ? etc?
  4. Any chance someone can tell me the theory and method behind infrared transmission and reception, how it works etc... universal circuit requirements... basically the principal behind it, etc etc... many thanks mcole
  5. can any one provide me with a pcb track pattern or circuit design plan for device that will do the following... count backwards from 99, however when a switchs contacts are broken the device stops on the number it was at.... thanks mick
