Two different projects will become ONE project for Xmas
Well, in previous tutorials <===> https://gustmees.wordpress.com/2019/11/03/first-steps-with-the-arduino-uno-maker-makered-makerspaces-coding-make-objects-rotating-with-a-stepper-motor/ <===> and in <===> https://gustmees.wordpress.com/2018/04/08/first-steps-with-the-arduino-uno-r3-maker-makered-coding-scrolling-text-with-8×8-led-matrix/ <===> we learned about the how-to to make objects rotating as well as to display a scrolling text on a LED Matrix. NOW, we will combine those two for a nice Xmas decoration.
When fixing a small object there isn’t any problem, you just drill a hole of the diameter of the axis of the Stepper-Motor and fix it with hot glue or instant glue. BUT, when it comes to make rotating larger objects it will become unstable!! We need then also a larger support plate to fix the object. I used two techniques, one with a copper-plate of 0.8 mm (was still in my cellar for 30 years…) and/or a single-sided copper-Epoxy plate. Copper-plates are expensive and single-sided copper-Epoxy plates are on a less expensive price. They are about 0.65-1€/piece on Amazon.
For our Xmas project we will use a plastic star with LEDs which will get fixed the following way, check below please.

As Xmas star I used one from Amazon, please check below:
Price is 14.99€, you may as well chose another one.
For the code (Sketch) please look at the following tutorial:

Two Projects in ONE
Once the Xmas Star fixed together with the Stepper-Motor, cabled and the the Code tested, WE fix our LED matrix with hot-glue, cabling it and running the Code for a last test:
