For my final project, I created wearable bluetooth enabled headphones that lets you communicate through color and led animations. Whether it’s to let someone know you’re busy or flirt with someone without using words.
The earbud component is 3D printed and attached to pre-existing bluetooth headphones. Using an Adafruit Feather nRF52 BLE micro controller with the Adafruit Bluefruit LE App, colors and animations for the LEDs can be changed using pre-programmed buttons and a color picker.
Here’s the instructables link for how to make your own!
