Various projects that emit photons in various pleasing patterns.
This repository contains these projects:
-
ARLENE - Arduino microcontroller connected to eight solid-state relays, ostensibly to electrical fairy lights of some kind. One button controls pattern displayed and speed.
-
LED Sign - Arduino controlled standalone display controller. It drives some recycled/recovered LED panels, approx 170x16px resolution. It implements a display buffer which it has routines to render text and graphics into, then blits it out to our weird display hardware.
-
Light Strand Engine - Arduino connected to a strand of WSxxx controlled RGB LEDs, and a couple buttons. A handful of patterns can be displayed and animated on the string of lights.
