C-Neopixel Fairy Lights

Neopixel Fairy Lights Activity

With the neopixel fairy lights, we are visualizing precipitation data, as simulated raindrops. There are three levels of precipitation, each represented by a different colour:

• Orange = Low precipitation.

• Light Blue = Moderate precipitation.

• Blue = High precipitation.
