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.

The Open Heart kit works great with the Arduino microcontroller, which has a low cost of entry, and is relatively easy to program. You can store up to 500 frames of animation on the Arduino, which could lead to some very complex animations. You can read more about the project in the video here.


  • Heart PCB
  • 27 red LEDs
