The sample code uses the LEDs at the right and left edge of the helmet's brim to signal you to turn, and uses the two LEDs in the center of your forehead to tell you "go forward" (solid blue) or "turn around" (blinking red). Customize to your own navigation style!
Oh hey! You weren't thinking of wearing this helmet in the rain, were you? The circuit isn't waterproof! We recommend removing the battery if you have to wear it in the rain, then waiting until it's completely dry before reconnecting.
