Motor only spins in one direction

Post by AidanBlair » Fri Sep 30, 2016 5:07 am

I recently have started playing with my motor shield and have come across a problem that I don't know how to solve. Using the example code for a DC motor shown on the quickstart page, I can get the motor to spin in one direction but not the other. I reverse which wire goes into which terminal and the motor only span in the opposite direction, so I don't think the problem is with the motor itself, more likely the program or the board itself. If it helps I am powering a 12v motor through a 9v battery. If anyone knows what I'm doing wrong or how to fix it that would be greatly appreciated!

Hi AidanBlair,

Sorry about the slow reply. Did you manage to fix the problem? If not post a picture of your current set up and I will see if I can spot any issues.
