I'm making a soccer car with arduino. And I have this undocumented motor control shield. So I don't know how to program it. I've tried to code it as if it be an H bridge, but is not working. Someone know which are the pins that I have to use? The plate is from DK Electronics, and says motor control shield for arduino.

Don't know why but the image can't be upload from my phone.

As I can't show more this way I have published on my Twitter account the image, if you can I'll be grateful. Link: https://twitter.com/ricardovaras_99/status/789249497322889216

This is the code I used guided by some internet articles about the Arduino's original motors control shield.

 pinMode(8,OUTPUT);       //Channel A Brake Pin Initialize
 pinMode(9,OUTPUT);       //Channel B Brake Pin Initialize 
 pinMode(12,OUTPUT);      //Channel A Direction Pin Initialize
 pinMode(13,OUTPUT);      //Channel B Direction Pin Initialize
  • No one will be able to assist you until we have more information. The photo may help, but more importantly is the documentation which begs the question:why did you buy a product with no documentation? Oct 20, 2016 at 22:42
  • would it be this in any case?? oddwires.com/motor-shield-for-arduino

  • You are going to have to try harder. A shield which you don't have a photo of, combined with code you haven't posted, and you are asking for help?

Judging by the fact that you agree it looks like this, a search reveals it is a knock-off of the Adafruit V1 motor shield.

Their page shows how to connect to it, and has example code and a library.

I don't really want to post a link-only answer, but the alternative would be to parrot the Adafruit page, which isn't really fair to them because this board wasn't even purchased from them.
