These cute individually-addressable (NeoPixel compatible) RGB LED stars on flexible silvery wire are great for coding up celestial room decor ⭐🌈
Addressable LEDs let you individually set each LED in the chain to a specific RGB colour by sending signals from a microcontroller. If you're looking for an easy, plug and play LED controller check out Plasma 2040 or Plasma Stick - just connect up the tinned wires to the screw terminals, apply USB power and you're ready to start making rainbows!
Alternatively, you could use a Raspberry Pi, Arduino, micro:bit, or other microcontroller to drive them - there are loads of different code libraries available (Python, MicroPython, CircuitPython, Arduino, and more).
The 5V / + / VCC wire on these LEDs is the one marked with dots. The DATA / PIXELS wire is the one in the middle, and the GROUND / - wire is the one on the other edge (that doesn't have dots).
The colour order of these LEDs may vary from batch to batch - if the colours aren't displaying as expected you may need to specify a different colour order in your code.
