Motors 1 and 2 not running #7

Closed AdamSchilperoort closed 6 years ago

AdamSchilperoort commented 6 years ago

I've followed tutorial after tutorial to run a robot using a motor-shield and these dependencies. When I run any of these test files, only Motor 3 and 4 trigger. Any ideas?

Have you tried Test_Motor.py ? Or if you have multimeter, measure voltage level at Motor Connector M1 and M2

I am having the same issue. My input voltage is 19v, motor 1 port output voltage is 2.25v. It's like it is still trying to draw its power from the pi instead of the attached power supply.

Hi acondra,

This might be due to some hardware problem. Or may be Motor Driver IC is not working properly.

My motor1 will run my 6v motor in reverse but not forward. I'm using the test_motor.py Is there a chance that something could be broken so it won't run my motor forward? Is the code not right for using a 12v battery with a 6v motor? I also have something between the shield and my motor that makes it run from 12 to 6V
