Here is an inexpensive programmable microcontroller that could be very useful!! Your programming knowledge from last semester should make using this board within your reach: http://www.arduino.cc/
- Arduino Duemilanove hardware description
- Arduino programming environment (compiler)
- Arduino tutorial home page
- EAGLE Layout files Δ for Arduino and Arduino "Shield" (template PCB that you can add circuits & componenents to plug into Arduino) updated May 9, 2009 (nicer layout that centers on 100 mm x 80 mm max EAGLE pcb layout and nicer schematic template

Here's a reference sheet for the LCD Display
