In the past week, I bought the most important part that I will use in my project. This is the RGB LED light ring. I soldered wires to the ring and tested it. Below are two images of the setup. I connected the ring to a 5 volt power supply in the top right of the upper photograph. I also connected the ring to the Arduino in top left of the upper photograph.
For my project, I would like to have a rotating piece in the middle of the ring with parts on it that interact with the light. After thinking about many possibilities, I have decided to use 24 acrylic rods. Each rod will be mounted to a piece in the middle of the ring that will hold it directly above an LED on the ring. The 24 rods will be able to rotate around the ring.
These are the items that I need to buy before I can move forward with the project:
- 24 3/16″ Acrylic Rods
- 2 Gears: 1 large and 1 small (will connect a motor to the rotating center piece)
- 1 Metal Rod (will hold the rotating center piece in position and allow it to rotate)
- Wire in multiple colors
