Arduino controlled lights
Last Christmas was my first Christmas in my very own house (was renting before) and so I was able to put up more lights than before. In the process of setting up the lights I thought about making them computer controlled (so as to sync to music etc)
I had some X10 appliance modules which did the job for turning them on/off at the right times of day, but there was so much lag that I couldn’t use it for anything fancy. As such I started looking around for how to do this properly. Most of the stuff I found was only available in the US and/or was very expensive so I figured I’d just do it myself :-)
