I have a really basic 433 MHz tx/rx pair that I bought and have not played with yet, but understand from reading that it is pretty simple to use the VirtualWire library for communication. I am thinking of an application where I only need to send three states (fwd/stop/reverse) to a motor, would like to do it wirelessly and think that involving even a basic MCU is overkill (having said that, I haven't done any work with MCUs other than Arduino...perhaps a PICAXE or something like that would be simple enough to be appropriate).
I though about just using two pairs (one for fwd, one for reverse and if neither had a signal then stop), but don't know about the possibility of interference.
I don't mind throwing some other electronics in there but don't have enough background to know what a good approach is. I know a little bit about 555 timers and thought you could send some different signals (e.g. different pulse width for fwd and reverse) on the tx side but don't know how you would decipher those on the rx side.
Any suggestions or a point in the right direction would be much appreciated.
