Here I control the rotation of a Mitsumi M42SP-5 stepper motor (50 ohm) with a potentiometer, using an Arduino Uno. Since the motor needs 12V to work, a ULN2003A darlington array is used. The code is ...

LCDMenu.ino is the original button and potentiometer code designed for the 513 step motors. ButtonMenuFineMotors.ino is a slightly modified testing ground which was used for the larger, more precise ...

In this tutorial we will learn basics and working of stepper motors and then will interface stepper motor with arduino uno and write the arduino stepper motor position control code.

In this project we are controlling DC Motor speed using PWM and we will be able to control the speed of DC motor with potentiometer and we can adjust the speed by rotating the knob of Potentiometer.

It’s a simple enough set-up in which a voltage controlled current source feeds the pot while an Arduino with a motor controller turns it through a stepper motor, and takes a voltage reading from ...

Rather than write a bunch of stepper motor code himself, he installed and ran a four-axis fork of grbl on the Arduino, turning it into a stepper motor controller.

This project makes a stepper motor control the position of a solar panel to make it turn to the position that it recieves the most light from the sun. After sundown (light dims below a set level) the ...
