Just brainstorming with myself here. I'd love to make a super basic RC car from the printer parts I've salvaged, and have it be all analog parts.
You could TX/RX on 1 frequency for 1 function, then another freq. for another function. Like 5MHz for turn right, 1MHz for turn left.
What about TX/RX on a single frq, but make it pulsed, and then change the duty cycle or say the pulse rate. So that you TX/RX at 5MHz, but turn right is pulsed at 50kHz, and turn left is pulsed at 100kHz, and you have some sort of circuitry that only responds to the pulse rate or duty cycle you choose.
Or maybe TX/RX with AM for turn right, FM for turn left. Or different levels of AM or FM for different instructions.
I have lot's of parts, I should start trying to make more stuff next year
