im working on a project that seems like it would be incredibly simple, but having trouble figuring a few things out. have some knowledge in comp programming, but none in electronics.
i need to use multiple rf transmitters all sending the same receiver. was thinking of using the MC145028 (but im not sure if thats what im looking for). After the reciever "hears" a transmission from a certain transmitter, it makes a beep. i dont want the receiver to "beep" from hearing that transmitter again for a certain amount of time. any suggestions or insults, haha?

Golly, I've used up all my good insults already today. Guess you'll have to settle for a suggestion.

You might want to look into a micro processor for your project. If each transmitter can send a specific binary number, the micro processor in the receiver could handle the rest of your requirements.

A very simple way would be to use a uC and prebuilt radio (it can get expensive).
