hmm not getting many direct answers, but I have made a circuit with my knowledge and parts on hand. Just would like to know of any type of rf transmitter receiver that I could use. Maybe one that has IO ports and whichever you set high on the transmitter gets mimic'd on the receiver? Im not sure if there is something so simple to use but I saw something like this a long time ago. It would have to be of general application and no specialist part for me to be able to get it here - South Africa. Thanks guys
