Howdy all, I'd like to start a project where I want to somewhat duplicate the lower end R/C car radio controls. The ones in particular that I am interested in have forward/reverse/stop and left/right/straight. Does anyone know of a good book or website that talks about these types of things in depth. I've got some info on simple audio transmitters/recievers, but nothing on how to enconde/decode a signal like perhaps TTL. I am hoping that I can find a way that will let me use fairly easy access components and stay away from PIC like stuff. Any ideas would be greatly appreciated. Thanks in advance.
