NAND Gate - CMOS Explanation

Controlling Neopixels without code. It is generally assumed that WS2812 / NeoPixel LEDs need a microcontroller.
Precise timing, tight loops, and carefully written code.
That is true in practice. But I was curious how much of that is actually required.

At the protocol level these LEDs only care about pulse width.
A longer high pulse is a one. A shorter one is a zero. The rest is just ordering and timing.

So I tried driving them without a microcontroller.
No firmware, no bit-banging, no CPU at all.

Just logic gates, counters, RC delays, and an oscillator.
After a lot of trial and error, it does work.

A Schmitt trigger oscillator provides the base clock, logic gates shape long and short pulses, counters split the 24-bit GRB frame into color windows, and another counter handles the reset timing. Buttons gate the pulses so colors can be enabled and mixed.

It is not practical and it does not scale.
A microcontroller is still the right tool.
But it was a useful exercise. It forced me to actually read the datasheet, measure signals, and think in terms of timing instead of software abstractions.

Meet the AX22 Modules — the new standard in modular electronics.

With 50+ modules (and more on the way!), the AX22 line covers everything from buttons, distance sensors, and microphones to receivers, display screens, and even micro motors.
Designed for versatility, every AX22 module snaps seamlessly into your setup whether you’re building smart devices, interactive installations, or experimental prototypes.

This is just the beginning. The AX22 series is growing fast, setting a new benchmark for modular creativity.
