I have decide to use the arduino board to power project E. In fact I think I may end up using 9 arduino boards in Project-E. I estimate that Project-E in total will have 13 microcontrollers. Here you can see I have a very simple circuit that I did based on this tutorial. It’s from the Make weekend podcast. These guys are awsome; however, Bre is no longer doing them so we’ll have to see what Make does in the future.
The arduinos come in many different shapes and sizes. You can even just grab the schematics online and build one yourself. Next to my main test board you can see a smaller version of the arduino which I am planning on using in project E.
