Arduino Show and Tell 1

Recently I have been learning about arduino, a microcontroller set up to help people learn about programming and electronic systems.
This video is NOT an instruction video, nor a tutorial. It's just a show and tell.
If you want to learn about arduino there are lots of great resources on KZbin.
One of my favourites is Paul McWhorter. I've copied the link to his 'New Arduino Tutorials' below.
