Changes

With my final project, I wanted to use some kind of interactive light device, and I stumbled across the idea of a POV (persistence of vision) bike wheel project. Though I'm not entirely sure about the final concept of the project, I want the text to change with the speed of the bike wheels.

Though I tried extremely hard to make the POV bike work, I couldn't with my still-novice electronics skills...And so, my next project idea ... HAMILTON, THE DONUT EATING ELEPHANT!

So what I did was make a felt donut with magnets inside. Every time HAMILTON the elephant is "fed" a donut, the reed switch closes its circuit, thus making the LED display on his hat go up one, making the hat display "EAT # KRISPY KREME DONUTS." Because I only had access to one LED display, the numbers only go up to 9, and then resets to 0.
