Steampunk Arduino programming

What?

I did a couple of workshops at the Fantasy Forest (Sudeley) event

Presentations

Here are the presentations I prepared, the actual programs got changed a bit, and the presentations got tweaked to match, I will put the corrected notes, and the latest code here in a few days (when I've unpacked the van, and got the USB sticks with the latest programs).
