Project Brief

Summary

UACs (pronunciation:/waks/ as in wax) - Unashamed Arduino Clones. Copying and building Arduinos at the LHS.

Overview

There are a number of Arduinos available as well as documentation to go with them. The aim here is to build Arduinos, based on the documentation available, to see how far it goes.

Arduinos

Here goes a list of the clones.

Arduino Uno

This might not be a good first choice, as it is, at the time of writing 08.10.2010, the latest and greatest. Anyway:

Arduino Diecimila

In theory, not as tricky to copy as the Uno as it can be assembled without an oven.
