Blinky Belt

Friday, July 22nd, 2011

My dad was ordering some parts for our Mechatron robot and he discovered a cool strip of LED lights that worked based on “RGB,” which stands for Red-Green-Blue. These are special LED lights that you can program to whatever color you want by combining red, green, and blue together. He asked me if I was interested in making a “Blinky Belt” that I could wear and would light up in various patterns. Of course I said yes! When the parts arrived, we started building immediately. We cut wires, soldered, and heatshrank. I learned how to tin wires for the first time. Then we soldered the strip of little lights to a tiny Arduino microcontrolller. Then we connected it to a belt buckle and a little pouch to hold the battery and electronics. After we were done with the building phase, we worked on programming it. We were able to program each little light separately so we could make any pattern we wanted, including violet, green, and other colors. Because it was the 4th of July, we made a wild red, white, and blue dancing pattern. It was fun to hold sparklers with a glowing Blinky Belt!

We’ll post a video soon, but for now, here’s a pic.

    Great project, I want to program my belt as well but not sure how. Kindly advise. Having different colour blinking is fun and bring happiness. Thanks for all your contribution.

    gg: Install the Arduino IDE, pull in the source code from the Adafruit site, then dig in. Adafruit’s Blinky Belt tutorial pages provide step by step instructions for how to do it. The source code for the Blinky Belt is pretty easy to read and modify.
