Alex Eames at RasPi.TV is currently running a series on the Raspberry Pi’s GPIO pins. It’s great to see this kind of blogging and it’s especially useful for beginners or those who need to know why you need that pull-down resistor, for instance. So far, he’s covered the basics and has now turned his attention to both inputs and outputs.

Of particular usefulness, the input article covers reading a simple button press and the output article covers lighting up an LED – basic electronics projects, but ones I’ll be returning to time and time again as I don’t seem to be able to remember how to do these simple things from one day to the next!
