As an exercise to make analysing and understand various wireless signals, both RF and infra red a simpler process, tarquinio has created am Arduino sketch and matching PC software to extract and display the signal being received. In doing so you can understand the data protocols and then create your own, for example to make your own remote controls or have your Arduino take over a few different wireless systems.
The entire project is documented well, start here for information and downloads. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're interested in receiving and decoding RF data over 315 or 433 MHz, check out our Receiver shields:
They're pre-assembled except for the headers, include two user LEDs for debugging or general blinking, and leave you plenty of space for prototyping circuitry. These shields can also be used in the the “Weather Station Receiver” project in the book “Practical Arduino” - it shows how to intercept the signals from a La Crosse weather station and decode them using an Arduino.
