Concept
Each LED has a tiny controller; one data wire carries a bitstream.
A little theory
GRB 24-bit, ~800 kHz. Current ~60 mA/LED full white — 30 LEDs ≈ 1.8 A. In the classroom, treat WS2812B NeoPixel Strip (5V, 1 m / 30 LED) as a intermediate part using Single-wire timing. Typical India street price is about ₹150–₹400. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
