Hi everyone, havent been posting here for a while now...And as always, I come with a doubt xD I want to activate a simple circuit (one that swtiches a transistor ON and OFF) via RF (any other wireless communication method is very well welcomed, except optical of course). The thing is, I want to activate multiple of this simple circuits with one Emitter instead of having one for each receiver. Is there any way to do this? I'll be taking this class in a month, so Im pretty green in the subject. Thanks.
