I have a Teensy 3.2 and Octows2811 set up to run a Christmas "mega tree". Three outputs run groups of 400 pixels at 5V: 16 strands of 50 for the tree and 4 strands of 50 for the star. Everything is working great and it's been exciting learning all about this. It's my first real try at an electronic project of any magnitude and it's all new to me.
My problem is that I'd like to be able to turn off some 120V decorations that will be nearby when the tree is running. If I was able to control them by relays, then I wouldn't have to stop at just turning them off, I'd sync them to the music and make them part of the display. Is there a way to operate a set of relays off of one of the remaining OCTO outputs?
I plan on purchasing more 3.2s and relay boards to control some 120V lights in my display next year, but they will be in a different part of the yard.
