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 .

  • Looks exactly the same, except for that some pin headers are missing. You could buy and solder them yourself. – chrisl Jan 18 '20 at 10:20
  • Thank you so much ! I find this pins from a old kit that I commanded , but they didn't mentioned that it comes without and in the image pins appear . – Ana Niorba Jan 18 '20 at 10:57
  • do you actually need those pins? – jsotola Jan 18 '20 at 18:30
  • Yes , I want to make a obstacle avoiding robot and I saw that more people use them – Ana Niorba Jan 24 '20 at 12:53

To complete @chrisl answer: Yes you need these pins to make the same robot as in the video. You can order them online and solder them (if you know how to solder and if you have the soldering material). Be careful with soldering ;)

For your information, the pins you circled in red are used to communicate with the Arduino pins A0 to A5, and provide +5V and GND. In the video, they are connected to the ultrasound sensor.

And please clarify what is your motor??? Do you mean the Shield motor driver? It is not the same. A shield is an eletronic board that you plug to your Arduino to do a specific task (control a motor, connect to wifi...). A motor driver is the electronic to control the motor. On your pictures, they are mainly the 3 components with 16 legs each.

  • Thanks ! It's a shield motor driver – Ana Niorba Jan 27 '20 at 20:17
