Nordic Pucks / Mbed 2 deprecated ir-puck Featured

The IR Puck can mimic arbitrary infrared remote controls. Built on the Puck IOT platform.

Dependencies:   Puck IRSender mbed

The IR Puck is a puck that can mimic arbitrary infrared remote controls. This is useful for controlling things like TVs, radios, airconditioners, window blinds, and just about anything and everything that can be otherwise be controlled by a regular remote control.

A tutorial for the IR Puck is available on GitHub.

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