This game was intended to be a rhythm based music game where the user controls the green flashing cursor to chase down and collide with a larger pinkish white circle before it disappears in order to cause it to "explode" and score a point. In order to make rapid cursor movement more easy two photocells were used for the x and y axis to allow quick and precise cursor control.

Speaker
Hooked up to AnalogOut p18 on mbed
Photocell
Hooked up to AnalogIn p15 and p16 on mbed.
On the photocells I did use potentiometer in series with the pulldown resistor for tuning the photocell controls to have a good control range depending on the current lighting environment.
