* Jason Griffey, Hacking on Hardware (3 hours): Come and join me for an afternoon filled with circuits and silicon! We'll be learning the basics of breadboards and simple circuits, and building our own input/output systems with Arduino. Learn the basics of programming to the Arduino...hardware will be provided, although you will need your own laptop (or are comfortable team learning with someone else). If you are planning to attend this hardware hacking afternoon, you will need to have the Arduino IDE 1.0.5 installed. The IDE can be downloaded from http://arduino.cc/en/Main/Software. ins
