Here are some examples of code in progress for 'my' Arduino (actually on semi-permanent loan from a friend). They are samples that do not need extra hardware - they write data to the serial port which is easily seen on a computer with a serial terminal emulator such as is built into the Arduino suite or hyperterminal in the Microsoft suite.

They provide a method for me to view the code (via web) when I am away from my home PC. Colours and formatting are provided by the Arduino suite. The code will appear here soon. There has been a change in the Arduino file structure and the earlier version was not completely compatible with the new version.
