Adventures with blinking lights
summary
Build uses Adafruit Feather (256KB) talking over Wi‑Fi to LED strips (tested with NeoPixel 60/m and older 32/m types) and a Node‑RED control center on a Raspberry Pi. Patterns implemented: a 15–30 minute sunrise sequence, meds and phone/door alerts, a stock-price strip, and a Cylon sweep. Problems solved: 7‑bit color accuracy, multiple power injection points for a 4m strip, and a missing capacitor that caused resets. Everything runs after firmware/library and power fixes; code and slides are on GitHub.
