Is this where I can find help?

[chrisco]

I want to build a small transmitter to transmit to another device that will light up and beep. I have no idea how to do this and am new to electronics in general. Don't need much range just a transmitter and reciever I guess. Can anyone point me in the right direction? Thank you in advance.

You can do it either via radio, or via IR, depending on your range requirements (and what you are wanting to do).

For radio, you can buy licence free modules quite cheaply, and Holtek sell encoder and decoder IC's, or you can make your own from PIC's or similar.

Thanks,
Can you tell me where I could find info on how to do this or how to design it. I really have no idea what I'm doing!

Maybe a kit is what you need:

They're available in several different types rf/ir and several different channel capacities. the circuit board is already marked up with what goes where..
