I bought a very cheap (like $1) 433 MHz TX/RX pair awhile back and have just started to play with it. All I want to do is remotely activate a switch. Lots of examples on the interweb of hooking each end up to an MCU and sending data, but I really just want to push a button at one end and have a motor turned on at the other end. Tried a little experiment with LEDs and the interesting thing is that holding the button down on the TX end only seems to produce a 'pulse' at the RX end...the LED doesn't stay on.
Other cheap/simple remote ideas welcome (it needs to work outdoors over about 30m with clear line of sight.
