In the Maker Shed: Open Heart kit V2.0
The Open Heart kit V2.0 is a matrix of individually addressable LEDs that allow you to create customizable animations when connected to your favorite micro controller. Attach it temporarily to fabrics with headers that you simply push through, or sew it into a project with conductive fabric for a more permanent setup. It’s “Charlieplexed” so you need only 6 wires to control the 27 LEDs
