I built this project a few months ago but never got around to documenting it until now. The idea for this project is to have an RGB light strip that can be turned on and off and have the colours changed from a phone app. It’s a simple idea with a relatively simple solution. While it is not fully supported, I think it is possible to get a Neopixel light strip working with a Raspberry Pi. But for this I used an Arduino Nano to operate the light strip and a Raspberry Pi to serve the website.
Adafruit NeoPixel Digital RGB LED Strip – White 30 LED – WHITE: These NeoPixel strips have 30 digitally-addressable pixel LEDs per meter and are very affordable and are only 12.5 mm wide, 10 mm if you remove the strip from the casing. This is the strip with white flex PCB, its identical to the black 30 LED/meter except it has a different color mask on the flex strip (read more)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
