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.
Arduino stepper motor speed control potentiometer.
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.
Circuit diagram for rotating stepper motor using potentiometer.
And the target position target pos and use this to control the motor.
Here it is possible to run the motor an infinite amount either way.
The pot controls how fast the motor runs and in which direction.
The 10k ohm potentiometer is used to control the speed of the stepper motor its output pin is connected to arduino analog pin 0.
A lot of m m jumper wires.
A 12 volt dc.
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.
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.
Some m f jumper wires.
The push button which is connected to arduino pin 4 is used to change the rotation direction of the stepper motor.
In this post we will learn about stepper motor control with potentiometer and arduino.
An arduino board arduino uno being a beginner friendly board is recommended.
The circuit diagram for the controlling stepper motor using potentiometer and arduino is shown above.
To energise the four coils of the stepper motor we are using the digital pins 8 9 10 and 11.
A stepper motor a potentiometer and an arduino the hw ingredients for this blog post.
