This is the circuit that we built. The white keyboard is connected to a PS/2 socket, which connects to the STK 500 board. The transmitter that we are using is located on the small yellow circuit board that is connected to the white prototype board. The actual transmitter chip is on the other side of the yellow circuit board. The receiver is located on the small green circuit board that is connected to the stand alone prototype board that we build. The prototype board has the ATmega32 processor located on it along with the necessary supporting components. The ATmega32 connects to the computer through a PS/2 socket. (The multi colored wire leads to the PS/2 socket at the back of the computer).
On the left is Luke Hejnar and on the right is Sean Leventhal. In this picture, we are using the wireless keyboard.
