 Create a platform that will aid newcomers in learning the basics of digital design  Run games such as Dance Dance Revolution and generate input signals to a student made digital scoring circuit  Student circuit will compare input signals to a device such as a dance pad, and will then provide feedback to the system so that the score can be calculated.

 An ability to generate inputs to a digital scoring circuit that a student constructs and read the output from that circuit  An ability to display custom, game play configurable graphics on an external monitor  An ability to read and interpret files, stored in the system, that specify graphical and audio game play features  An ability to control micro controller I/O functionality from the embedded host  An ability to allow definition of multi-player games

 Hardware Requirements for Game Host  Comparable Game: Frets on Fire  Guitar Hero Adaptation  600 MHz, 128 Mb RAM minimum  Comparable Game: Dance Dance Revolution by Konami  400 MHz, 32 Mb RAM minimum

 Intel Atom N270  Exceeds minimum requirements for comparable games  Integrated graphics accelerator  x86 architecture  Allows java portability  Eases development

 PIC 18F4455  48 MHz, 24k Flash, 2k RAM  Currently 6 pins of 40 not used  Hardware Requirements for Micro Controller  USB connectivity  RS232 connectivity  20 general purpose I/O pins

 Specified routing to use at most 45 degree corners  Accounted for the calculated power traces of width 30  Boosted trace spacing margins to 9  Used min trace size of 12, recommend trace sizes of 15, max of 20
