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

We used a CD as a ridged platform to mount our zoetrope. A wooden assembly was used to mount the zoetrope to our motor.IMG_3253


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.
