Early Mouse Example
This is a University project mouse, that runs on three wheels, two for up and down, (the second wheel is there to keep the mouse balanced). The single wheel is for left and right movement.
Additionally to the movement wheels, there are two clear ones with black dots on them, which travel through a light sensor, when the light is broken by the dots, movement is sensed, and the cursor will move on screen.
