The Arduino board is an ATMega processor on a common system interface board with a great little bootstrap loader program built in. This board has multiple Input/Output capability with various methods of talking to peripherals, sensors, and relay driven devices. There is a large community of users and a great many resources available to support a wide array of projects with this board as a programmed controller.
The workshops we put on are aimed at showing how the Arduino can be assembled and programmed using a simple, non-soldered breadboard. This is a basic level of instruction that will allow the attendee to expand their understanding and build a more complex unit of their own with the techniques from this workshop.
