What you need

• 1. Cardboard from carton box

Connections

Neopixel

1. Count the number of LEDS on the strip or ring. Specify which pin the neopixel is connected to.
2. Take note of the arrow direction .
Din is the input (connect to the micro:bit). To connect 8 leds or more (recommended but a lot of
times, I have no problem running 12) in a strip requires an external supply.
