1.if i want to make a simple remote controller and reveiver ,e.g. when
i pressing button A from the controller,then LED A will turn on in the
receiver side,i don't want the use IR TX &RX,so i want to use RF, but
i have no idea to make it,so anyone can give me a simple diagram,or
give me some web sites about the RF.
2.i have found some diagrams about them ,i think they are very
complex for me ,in the diagrams a component called inductor,what is
this? , How to use it?
3.if i want to make a simple bug,is it principle like the remote
contoller? i have found some web sites only teach how to make the
transmitter,they use radio to work as the receiver, that means anyone
turn their radio to the same band ,then they also can receive the
singles?
thanks
