we are using the Dual MC33926 Motor Driver Shield in conjunction with Arduino Uno and a 12V/~1A DC motor.
When using positive speed values everything works fine - with the same negative values we get a lot less power and speed.
Also it seems to us that it gets hot much faster when spinning with negative values.
We have the same problem with all other motors we tested.
We use the http://github.com/pololu/dual-mc33926-motor-shield library.
md.setM1Speed(400) works perfectly - md.setM1Speed(-400) not…
Thank you very much in advance and please let us know if you need any more info.
All the best,
