These wireless transmitters work with our 434MHz receivers. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair.
Note: These modules are indiscriminate and will receive a fair amount of noise. Both the transmitter and receiver work at common frequencies and don’t have IDs. Therefore, a method of filtering this noise and pairing transmitter and receiver will be necessary. The example code below shows such an example for basic operation. Please refer to the example code and links below for ways to accomplish a robust wireless data link.
Note: Color may be blue or green, but they are the same module.

Got it, plugged onto breadboard, hooked up Arduino, wrote a little test program, and it did things. Now bigger challenge of making my larger project work - still writing code!

This comment is more to say how good proto-pic are on the delivery. Ordered at 11pm on a friday and received it the next day. I might have been lucky with the post but they always delivered on time or earlier and well packaged.
On the product side, it's small, easy to setup (just 4 pins) and has got a good range even through walls.
I bought it to use with Maplin remote plugs. Using this amazingly easy to implement code from here: http://www.fanjita.org/serendipity/archives/53-Interfacing-with-radio-controlled-mains-sockets-part-2.html
All prices are in GBP.
