Controlling Christmas Lights using Midi

Some time ago I’ve posted how to control a relay using Midi. This was a preparation to the christmas lights midi-control. Now let’s see, how it works.

Update: You can control and watch christmas lights yourself using Midi at http://heckenlights.org. Heckenlights are my publicly controllable christmas lights.

My basic idea was: Let start with something simple but expecting a great result. So I got and connected an ethernet-based relay (Did not have such a long USB cable) to a bunch of christmas lights and my Raspberry Pi. In the next step I created a controller programm and some midi files for having content. This together enabled me to control christmas lights synced to some christmas music. The control program maps the note on/off events to relay on/off events using the relay’s output channels. Below you can see how it’s connected.

See how it looks when all the components are connected and working
