When this program is run, it will clear the display and then write a 0 to it. When the button is pressed it will show a random digit from 0 to 6. This will stay on the 7-segment display until the key is released and pressed again. To stop the program press CTRL and C at the same time.

The Python Code for all the project can be found at http://www.sf-innovations.co.uk/projects.html.

Project 4:Driving a tri-colour LED

In this project we are going to drive a tri-colour Red/Green/Blue (RGB) LED and control the brightness of each of the colours from the keyboard. By mixing these colours we should be able to get a wide range of shades.
