ESP32 WS2812B NeoPixel Strip Control
WS2812B (NeoPixel) addressable LEDs are smart RGB LEDs that can be controlled in a daisy-chain configuration via a single data pin. In this project, we will control an 8-LED WS2812B strip using the Adafruit_NeoPixel library to create a smooth rainbow animation. While the ESP32’s 3.3V logic level works seamlessly with most WS2812B components, we’ll demonstrate a solution using a 470Ω series resistor and a 1000µF capacitor in case of instability. The animation is achieved by shifting the hue value
