“This neat little sensor works perfectly with the Gemma as well as the Flora. I've hooked it up to a Gemma that drives some neopixels attached to a headband. The sensor detects a colour, and the neopixels reflect that colour. It's worth noting that the RGB readings from the sensor need manipulation - you can't just send these values direct to the neopixels - but the provided example code from the Adafruit library shows you how to do this.”
