Based on where you live, you have possibly viewed a house with crazy glowing Christmas lights that change color and dance to music. Almost every neighborhood or city has "that one home" that goes all out for the holidays annually. In my area, that house is mine. If you have ever wondered how those screens work and what you will need to create your own, this is going to be an overview of all the elements and how everything works together.
Three key things make up a Christmas lighting show: the sequencing, the control circuitry, as well as the lights.
The lights are organized to form different props like leaping arches, snowflakes, stars, legatees, and much more. You couple those lights with power supplies and controllers to make them function as expected.
