This attractive, individually-addressable (NeoPixel compatible) RGB LED wire is perfect for making your own programmable fairy lights. 🌈
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).
Note that the colour order of these LEDs is RGB, you may need to specify this in your code.
