Wire up some WS2812/Neopixels to your badge and display some simple patterns. ## Features - Joystick adjusts patterns and brightness - Patterns: Rainbow, slower rainbow, all on, all off, 3Hz flash - Currently up to 80 supported, easy to change by editing the code. - Adjustable (in code) max brightness to save power ## Wiring There is probably some issue with this wiring, the LEDs often come on dimly after powering up. ### Data I soldered to the input pin of the Torch LED D1 (see the [schematics](https://github.com/emfcamp/tidal-docs/blob/main/schematics/tidal-bot.pdf)) but J3 pin 1 would also work (and be a bit easier) I initially tried just using the expansion pins, but without a level shifter (already present for the torch) the WS2812 won't work. ### Power An LED strip requires quite a bit more power than the badge battery can likely take, and 5V rather than 3.3V. I have the power line connected to the 5V pad on the top board. I also soldered a USB cable to the pads on the top board, so I can power the strip (and the badge) from a USB power bank. If you have a USB-C power bank, this isn't needed.
