The Scope has a 12v 5wire stepper motor, need to add speed contorl with the cheapest simplest arduino board and stepper controler combo, speed controled by a potentiometer all standalone, with a overide on the potentiometer to speed up or slowdown switches. seen this done with an UNO board, would a smaller board do the same?
Board i'm thinking about is the arduino Nano, would it use the same programming and connections?
Yeah, same programming and connections for the Nano.
The main thing to look at is the chip. Uno and Nano can both use Atmega328 chips, so most things are completely interchangeable. Anything with a different chip will have some differences.
I know someone has measured a setup with the original controler which i don't have at 0.34Amps, the stepper is heavly geared down and has 5wires conecting it. Spares are not available as the manufacturer went belly up several years ago. So i'm hoping to us a Arduino setup to repace the missing controler.
So far it's looking like Arduino Nano, a small stepper board and a varable risitor to control rotation speed.
