Make objects rotating with a Stepper-Motor

Well, in a previous tutorial <===> https://gustmees.wordpress.com/2018/09/19/halloween-project-with-skull-arduino-blinking-leds-and-scrolling-eyes-maker-makered-makerspaces/ <===> we created a Halloween Skull and it was fix, didn’t rotate. Fun? YES, BUT more fun when it is rotating by using a Stepper-Motor; looks then as it would observe, control the space around it 😉 And it is very easy to create, only a Stepper-Motor, an Arduino NANO and a bit Code; the rest is a bit manual work to fix mechanically the motor. And with the right tools the mechanical work is a piece of cake 😉 Let us have first a look of the parts and the costs, followed by the mechanical works and then the code (Sketch) for the Arduino.

The mechanical works

First of all chose on what material you would like to fix the Stepper-Motor: this could be metal, plastic, cardboard or wood. As I like recycling, I ask in the Supermarket to get an empty wooden wine box. The Supermarket sometimes opens a six-pack of wine bottles in a wooden case (box) and they are happy NOT to recycle it themselves 😉 Here below an example for a Halloween project…

Desription:

Drill a hole with a 6 mm drill in your support, then use the 32 mm Step-Drill to make the hole diameter fit to the diameter of the Stepper-Motor. Fix the Stepper-Motor. I used a copper-plate for having a large surface to fix the chosen rotating object. The axis from the Stepper-Motor is made from brass and that fits very well with copper for soldering them together. For the soldering you need an 80 Watt solder iron with a temperature of 430° C (806° F). Before you start soldering: clean the copper-plate, take off the patina first!!

Halloween Project with Skull, Arduino, Blinking LEDs and Scrolling Eyes

Soon is Halloween, so let us create a scary project while coding and DIY (tinkering a bit…). The tutorial is made for people who don’t have a 3D-Printer, we will use a 21 cm plastic Skull for 13€ bought on Amazon, 3 ARDUINO NANO’s and two 8 mm WHITE LEDs to realize this project. First let us have a look how the project will look to give you the right motivation to start it, check the video below, please:

.

.

As you might have realized while watching the video, there are 3 different effects in it:

• The rolling eyes, we were talking about it already in following tutorial:

  • First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | 24×8 LED MATRIX | Rolling Animated Eyes

• The blinking WHITE LEDs in the nose, please check the following tutorial below:
  • https://www.instructables.com/id/Multiple-Blinking-LED-on-the-Arduino/
• The blinking LEDs around the teethes, we are using WS2812B Addressable RGB LED Strip (6 LEDs), check tutorial below, please:
  • https://randomnerdtutorials.com/guide-for-ws2812b-addressable-rgb-led-strip-with-arduino/

In the above mentioned tutorials, you will find the wiring as well as the codes (Sketches):

First start with one of the 3 projects, make the wiring and upload the code to the ARDUINO Nano and test it. IF it is working start the second one and so on… Once finished the above mentioned we will need to integrate the hardware into the Skull…

Check below, please, the different steps…

SO, we have seen now ALL the necessary steps to make this project working, up to YOU now to bring in the electronics into the Skull and seal the Skull later with hot glue. You can use the above showing cable solution or to try to put everything on a Strip-Board and solder it; YOUR choice! 😉

Idea: You could try to include as well a proximity sensor which enables the playing of the devil laughter in the video 😉

How? Check below please:
