If you’re heading to a convention or conference this summer and you want to stand out, check out our latest tutorial from Erin St. Blaine: make a bluetooth controllable LED glowing badge lanyard. Hang your badge with style and control the colors and animations with your smart phone. From the guide:
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!
Head over to the Adafruit Learning system for the full tutorial:
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
