At first, I wanted to make a bird's eye view of a city. I bought a motor to make a conveyor belt to make it look like the cars were driving on the ground. I picked a tissue box to be the stage for the diorama. I painted the inside and outside, and I added reinforcements out of wood to keep the box from warping. 

Then, I had a new idea. I could still keep the box, but I would change what would go inside. Instead of a city, I decided to make a party with a disco ball. I would use the motor to rotate the disco ball, two lasers would shine on the ball, and an LED would change color. Once I had the parts I needed, I started to program the Arduino at home and wire the electronics at school. 

Anne found an actual mini disco ball, and I decided to use it instead of the one I had made. I added some sparkle on the walls, and I mounted the lasers on the side. I added mirrors on the floor, and attached the disco ball to the motor. Once I added the finishing touches to the inside and the code, it was done. I am really proud of it, and I think it is unique. No other dioramas I have seen have incorporated this amount of electronics.
