Electromagnetic Arcade Game

For ME 218A I created a quadruple slider-crank mechanism, powered by a continuous rotation servo, which bounces ball bearings into four electromagnet’s zones of reach. The keys on a numpad acutate the electromagnets and a potentiometer controls the direction and speed of the slider crank mechanism. When you successfully stick a ball bearing to a magnet, an IR LED sensor tells the TIVA microcontroller to turn on the indication LED corresponding to the magnet number. My next step was to make a game out of this whole thing, e.g. the microcontroller would control the slider-crank irradically and you would have to use the potentiometer and numpad to stick all 4 ball bearings to the magnets within 30 seconds, but I unfortunately ran out of time. This was a very difficult project because I didn't have a group to work with but it was a great learning experience. Completed fall of 2015.
