Get noticed and stand out at the convention with this DIY light-up badge lanyard. Control the color and brightness with your phone over Bluetooth (BLE) with the Adafruit BlueFruit app. This is a great conversation starter on its own. Pair it with a PyBadge for extra geek points, or make a lanyard for everyone on your team and control ALL the colors. Make it red when you're running late, green when you're ready to network, and indigo when it's time to relax with a cold drink.
This is an easy-to-assemble project that requires a little light soldering and some drag-and-drop code. Most of the work is already done for you!
This is the easiest time I've ever had setting up a Bluetooth-to-microcontroller connection. Get the software installed and .. it just works. Hooray!
Additional Materials Needed
- 1" tubular webbing -- about a meter long in your preferred color
- Swivel hook for holding the badge
- Hot glue gun
- Soldering iron & accessories
- Needle & thread
You'll also need a smart phone that's capable of running the free Adafruit BlueFruit app.
