From the new book Wearable Tech Projects by Sophy Wong – light up your wardrobe! Use the same simple Adafruit Gemma M0 circuit to add a splash of colour in three different ways.

With a few modifications, one circuit can make many different projects. Here are three wearable ideas all built from one simple circuit. First, we’ll make an LED headband from start to finish. Then we’ll use the same circuit to make both a Star Trek- inspired combadge and a light-up hoodie. In all three builds, we’ll play with capacitive touch and make a button using conductive fabric. This is a great technique for wearables, and the Gemma M0 from Adafruit makes it easy to incorporate into projects.

The circuit is programmed for the desired lighting with CircuitPython, the easy to use code that you can edit in a text editor and copy to the Gemma like a flash drive. Experiment with effects in minutes to get the right look (compared to hours in Arduino).
