The Raspberry Pi provides a great platform for experimenting with basic electronic engineering and low-level computer programming. This sample project should give you a starting point for some of the interesting electronics projects that can be completed using the Raspberry Pi.

Note that all of equipment mentioned in this project is available to use in the DCS iLab.

The Pi-Face: Now the iLab has access to Pi-Faces, this tutorial can be completed more easily.

Example 1: Getting a LED to Light Up

The aim of this introductory project is to learn more about how the Raspberry Pi physically connects to other components, by lighting an LED using the Raspberry Pi's power source.

This example has been adapted from Drogon.Net, based on the equipment available in the DCS iLab. You can view the original project instructions here.

Step 1: Gathering the Hardware

Before we can do anything with the Raspberry Pi, we need to gather a few pieces of hardware:

1. The Raspberry Pi
2. A Raspberry Pi Power Supply
3. A Breadboard
4. 2 Wires
5. A 270 Ohm Resistor
6. An LED

Step 2: Connect the Components

Next, and before connecting the Raspberry Pi to its power supply, assemble the circuit using the following diagrams.

Step 3: Watching the LED Light Up

Once you have correctly assembled the circuit, plug the Raspberry Pi into its power supply. The LED should now light. If it doesn't, disconnect the power supply, reverse the LED, and try again.
