This is a demo page for a working version of Frogger for mbed. The game functions using a 6 by 6 grid which Frogger can jump around on in order to avoid cars moving two separate directions at two differing speeds. Frogger must also navigate his way across a small stream by hopping on lily pads or else splash into the water. Reaching the other side signals victory. This demo requires and uses the mbed processor, an LCD screen, a digital thumbstick for user input, an SD card reader for storing soundbytes, a speaker for playing audio, an H-Bridge to connect to a DC motor used for haptic feedback, and an external 5 volt power supply.
