I will be running an Arduino workshop at the UKUUG (Unix UK Users Group) meeting this summer.
Partly as a consequence of this I have developed a number of workshops and a course which can be found on the absolute beginners web site,
I am planning a number of more advanced workshops early in the new year
- Arduino and Bluetooth
- Arduino and WiFi
- Arduino Robotics
If you have any experience of such courses that would be of great help.
