Driving NeoPixel LEDs Using Pure Hardware - No Microcontroller, No Code A recent video by Axiometa explores an unusual electronics challenge: driving addressable NeoPixel LEDs entirely in hardware, without any microcontroller or code. Since WS2812-style LEDs normally rely on tightly timed digital data from MCUs, the project asks whether basic components like counters, timers, and logic gates can replicate the protocol. The goal was to generate the required pulse… |
