Servo Motor Controlling with Arduino

Hello friends, after some time here another post about motor controlling and this time I am going to control a Servo Motor with Arduino Uno.

Servo motor is an essential device for all Robotic lovers. For an example, to control a Robotic arm, You need a servos.

Using Arduino, you can easily control servo motors. Arduino has a special library called "Servo"

Here are some images I took while I do the experiment.

For source codes and echematics, please follow the Arduino official tutorial page.

Stepper Motor Controlling using Arduino

I found a stepper motor from a broken printer and I was thinking how to control this. Because controlling an stepper motor is not easy as controlling a simple DC motor.

First I found that the stepper was a uni-polar type one. Then using Arduino stepper library, it was a peace of cake building this project.

I purchased ULN2004A motor controller and here is the schematic from Arduino official tutorial.

This is an interesting project because you can control the speed of your stepper motor using potentiometer. I used a 50K (Kilo Ohms) one.

Here is an image of my project setup :

Here is the video of my project:

And here is the Arduino official tutorial page link. You can find the source code from this link. Have a good day!!
