Nordic Pucks / Mbed 2 deprecated cube-puck Featured

Rotate the Cube Puck to invoke actions on your smartphone. Built on the Puck IOT platform.

Dependencies:   Puck MPU6050 mbed

The Cube Puck is an innovative bluetooth-enabled remote control device. It is a six-sided cube that can be rotated to any of its sides to invoke actions linked to that side. The cube puck is completely customizable and therefore also quite versatile.

A tutorial for the Cube Puck is available on GitHub.

Tutorials and in-depth documentation for the Puck platform is available at the project's GitHub page
