This week we built our own zoetrope animation devices. The spinning device has slits in the side and a sequence of images can be seen through the slits. Because of persistence of vision (POV) our eyes believe that the image appears to be moving.
Step 1: Wiring the breadboard
First we added two switches to the breadboard, one to control on and off, and the other to change directions. We also added a potentiometer to control the speed of the motor. This was all achieved using the H-bridge integrated circuit that came with our kit.
Step 2: Adding the motor
We attached our motor and a 9 volt battery to our breadboard. The battery is responsible for powering our DC motor, while the Arduino powers the switches and H-bridge.
Step 3: Building the zoetrope
Step 4: Testing the animation
We tested the zoetrope and, though a bit fast, we could see the animation playing through the slits in the side of the zoetrope.
