Review on 🌟 BTF-LIGHTING Chasing Dream Full Color Twinkle Decorative Lights: 5m/16.4ft 50LEDs WS2812B IC Fairy String Lights for Kid's Bedroom, Christmas Tree, Festival Party - No Power or Controller Included by Crystal Garrett

This is one of my favorite Neopixel/WS2812b compatible configurations. This particular BTF Lighting product is my favorite string of lights. I feed them my own animations running on microcontrollers. You can of course use any 5V WS2812b from BTF Lighting or another supplier if you don't want to program the MCU yourself. Why don't you program them yourself? You can do interesting things with analog or digital data interpolation, use math to display fractals, create eye-catching animations, analyze an audio spectrum, or use a volume meter. The magic lights just flicker! Today's photo is from my office where I created an LED monster using a bunch of individually addressable WS2812b LEDs. I'm testing the power consumption and measuring where power needs to be applied to drive 1200 LEDs in series using a data pin on a RP2040 microcontroller with external 5V power support, around 2 amps. The individual LEDs are tiny in translucent plastic. There are plenty of these at full brightness, but they can be scaled down to about 1/12th the power to make the flicker weaker. As with all WS2812b products, you can send one of 16 million colors per pixel from the controller. There are CircuitPython, MicroPython, C/C++, Arduino, and MakeCode libraries. I use CircuitPython on MCUs and CPython with Adafruit's Blinka module or FastLED with C/C++. Or you can of course use any WS2812b compatible 5V controller. I buy many different configurations from BTF Lighting. They're not the cheapest, but they're reliable and generally not bad. You look great!
