When you turn the Motor controller the ball spins and you can control the speed. There is also a button glued down on the side to turn off and off the lights. Materials: Leds, motor, batteries, wires, switch, soccer ball, cardboard and motor controller. I used soldering iron, hot glue gun and screw driver. The hardest part was keeping the wires organized. The most fun was soldering the wires and the leds and stuff. I learned how circuits work and I got much better at soldering. If I could change something I would make it so the ball would spin slower and the lights were inside the ball. Theres a video on Seasaw and here is a photo and I don't have a photo of early stage I did not know I needed one and I can take a picture of my sketch next class.
