Arduino bipolar stepper motor control code.
Arduino stepper motor speed control potentiometer.
The pot controls how fast the motor runs and in which direction.
We have used the 28byj 48 stepper motor and the uln2003 driver module.
We will be using the accelstepper library to control the speed and acceleration of the stepper motor we want the motor to move in relation to the rotation of the potentiometer.
In this post we will learn about stepper motor control with potentiometer and arduino.
A stepper motor a potentiometer and an arduino the hw ingredients for this blog post.
Commercially stepper motors are used in floppy disk drives flatbed scanners computer printers plotters slot machines image scanners compact disc drives intelligent lighting camera lenses cnc machines and more recently in 3d printers.
Here it is possible to run the motor an infinite amount either way.
Circuit diagram for rotating stepper motor using potentiometer.
A stepper motor driver be it l298n af motor shield a4988 or drv8825 the latter two are recommended since the current output of these drivers can be adjusted.
Since a potentiometer can change value even when we are not touching it we are moving the motor only if the potentiometer value has changed 6 or 6 from the previous.
This approach is a bit different.
Dc motor is the most used motor in robotics and electronics projects for controlling the speed of dc motor we have various methods but in this project we are controlling dc motor speed using pwm in this project 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.
A 12 volt dc.
An arduino board arduino uno being a beginner friendly board is recommended.
Some m f jumper wires.
And the target position target pos and use this to control the motor.
The circuit diagram for the controlling stepper motor using potentiometer and arduino is shown above.
The push button which is connected to arduino pin 4 is used to change the rotation direction of the stepper motor.
