The miniDSP UMA-8 microphone array, with onboard direction detection, echo cancellation, and noise reduction, has a wide variety of applications. As a fun application, we wanted to build an app note on how to control light. Think of Philips HUE but DIY and built from scratch with your RPi, a UMA-8, a low cost landtern. Most importantly, we also provide a default starting code and IBM watson step by step instructions to setup your environment. What else could ask for?

 "Let there be light!"

So enough wiht the talking, let's get started looking at clear step by step instructions posted on instructables website.
