Arduino radio communication

Once again, I have ordered the wrong hardware from eBay. This time, it was a set of 433MHz radio transceivers for "Arduino". The majority of these come with embedded circuitry for sending and receiving bits. The ones I ordered, however, did not. The transmitter emits power when its data line is powered. The receiver emits a varying voltage, which can be ADC'd back into a value, ~1 -> ~800. This is…
