Warnings

While most of these circuits may interface directly to the RPi, the use of a buffered interface (such as the one supplied by the Gertboard) is recommended which will help protect against damage. Alternatively, experiment with one of the Alternative Test Platforms.


Extreme caution should be exercised when interfacing hardware at a low level, you may damage your RPi, your equipment and potentially yourself and others. Doing so is at your own risk!

Aims

The purpose of this guide is to enable control of an LED via the GPIO pins of the RPi.

The first stage will be to build the hardware we are going to use, and then we shall look at the software which will drive it.

Note:
Until RPi devices are available, I can not confirm this will work on a real RPi.
For now, I shall be using the TI LaunchPad (see  Alternative Test Platforms
for details) to test the hardware on.
