I am a beginner with Arduino. I wanted to make an Arduino obstacle avoiding. So I ordered last week an L293D Shield Motor Driver and I don't know if what I receive is a good item. The first picture is how it looks on the site and the second picture is what I got.
I saw that if you search for this motor you get results for both motors, but they are not the same. And I saw in this tutorial, this person using a motor like mine https://www.youtube.com/watch?v=ydDvoknlJ9M and then he switched to the motor in the first picture.
Questions: Are these motors the same? Should I request a return? If they are the same, how can I add the pins (as shown in the third picture?
Again, I am a beginner and I would appreciate if someone can help me.
