To get started with the basics of electronics we are going to look at a very basic circuit with a switch that can turn a light on and off. Okay this may not be exactly what you are hoping to achieve in terms of creating the latest computer controlled electronic gadget, but that will come a bit later. For the moment we need to look at the basics and learn to walk before we can run.

Lets first look at some basics about electricity and how it works. I've kept this to the very minimum so that we can get on to creating our first circuit.
