Rotating Display

My teacher wanted me to make something for this challenge, though it was required for me to actually compete. Though I thought it would be fun to anyway. Leading to me making this Rotating Display, plus it tis the season so why not a Christmas tree.

-3D printed parts

-28BYJ-48 Stepper Motor

-Mega Controller Board

-LCD1602 Module (with pin header)

-ULN2003 Stepper Motor Driver Module

-6 Female-to-Male Dupont Wires

-USB Cable

This can definitely be done with a lot less parts by using a different motor. I just use this one specifically because it was the best for this build in my possession. All these parts are from a ELEGOO UNO starter kit (Other than the 3D printed parts of course).

You want to make your base able to the stepper motor inside and stay secure. My base is a 2.5in x 2.5in x 2.5in cube, with a hole specifically made to fit the stepper motor, doesn't have to be perfect, just close enough to be able to screw it into place, making sure it doesn't move around.

On the back has a rectangle opening so that the wires for the motor can be easily connected to the driver module. It has a length of 1 in and a width of .5in.

The lid is made to fit into the hole on top of the box perfectly, meaning all you got to do is slide them together. These two parts are not supposed to touch because it stops the motor from spinning when they do.

So, the hole in the cover has a radius of 1.30in, while the platform is a bit smaller with a radius of 1.25in.

Looking at the bottom of the platform, you'll see a little rectangular indent. That so the tip of the motor can attach to it. Letting it rotate.

What to connect:

-8 connects to 1N1

-9 connects to 1N2

-10 connects to 1N3

-11 connects to 1N

-GND connects to -

-vin connects to +
