A blogger called Eric has written up a simple piece of code, and an accompanying Fritzing circuit diagram, of how to read a switch input and turn an LED on and off. It’s a simple example, but does show you how simply this kind of thing can be done. Read it here. Don’t worry if you’ve got a model B, by the way, you can just use different pins to do the same thing as on the B+/Pi 2.

Raspberry Pi on CBBC Technobabble
Children’s technology show CBBC Technobabble went to Pi Towers recently. Reporter Frankie Vu interviewed the Foundation’s Carrie Anne Philbin in which she introduced the Pi and lots of cool stuff you can do with it, like build a weather station or a robot. Rather chuffed to say Pi Wars even got a mention and a quick clip! Check out the Foundation’s blog post here or go here to see the programme (skip to about 4:10).
