Wires? Where we’re going we don’t need… wires…. Except for power, ground, programming, buttons, others sensors, etc….
This week, we’re continuing our looking at the Arduino, the most popular microcontroller platform on the planet. We’ll be introducing the versatile Radiohead library, and using it to drive some inexpensive ASK/OOK 433 MHz modules to pass lightweight wireless signals between two Arduinos.

- Working with the Radiohead library
This week we’ll be making extensive use of the Radiohead Library to handle wireless communication. You can download it from the link above. Notice that if you Google “Radiohead Library” you also will see github links to Sparkfun’s fork of this library, which doesn’t seem to be as up to date – I recommend using the source from Airspayce above.
