Auto spin 3Dscanner prototype

I wanted to 3D print a 3D scanner but most of the ones on here are 20+ pieces and it's manually cranked. I decided to use some electronics and design my own.

THIS IS A VERY ROUGH DRAFT BUT IT WORKS FOR MY OWN USE. I WILL PROBABLY IMPROVE ON IT MUCH LATER AS TIME PERMITS.

Code: The code is a simple one I got online since all I needed was the step motor to run in a slow constant motion and I have not worked with step motors previously. There are several other ways to do this and I may code it later to be activated via IR remote. That code is also attached.

NOTE: You can increase and reduce the speed it spends by editing the time_delay variable I added. The higher the delay the slow. Currently set to 10.

As for assembly, they all fit nicely in the slots but I use velcro to keep the Arduino in place and I scaled down a 3d printed bolts with a chunk cut out across the head to use with a flathead into pre-drilled holes for the ULN2003. I did not include that file since it would
