I am a beginner with Arduino . I wanted to make a Arduino obstacle avoiding so I commanded last week an L293D Shield Motor Driver and I don't know if what I receive is the good ithem . First picture is how it looks on the site and the second picture is what I get .
I saw that if you search for this motor you get resolts for both motor , but they are not the same . And I saw in this tutorial , this persone use a motor as mine https://www.youtube.com/watch?v=ydDvoknlJ9M and than he switch to the motor in the first picture . Questions : This motors are the same ? Should I request a return ? If they are the same , how can I add ... I don't know how to say ... that thing that is in the third picture ?
Again , I am a beginner and I would apereciate if someone can help me .
