I'm currently trying to make a automatic chess game, where the pieces move "alone". It's basically a electromagnet moving under the board. To move this electromagnet, I am using shafts with carriages, and a pulley system controlled by stepper motor.
My problem is that I don't know how to power my project.
I have 2 stepper motors (links are below) that work at 2.8V and 2A. To control these stepper motors, I use 2 A4988 modules (with an integrated potentiometer to control the current). The brain of my project is an Arduino Mega (which also needs to be powered). As for the electromagnet, it works at 12V and 0.25A.
I'm following this tutorial for my stepper motors :
However, in this tutorial only one stepper motor is controlled.
My question : has anybody got an idea to power:
- 2 stepper motors,
- 1 Arduino Mega,
- 1 electromagnet,
with only one power supply ?
PS: is it a problem if the stepper motors don't get their rated power ? I guess they will be less powerful but that's not a problem for this project.
Possible power supply ?:
For the moment, I haven't purchased any of these components so if you have better ideas, feel free to propose them.
I'm a noob in electronics so please be indulgent,
Thank you very much for your help !
