Hello,
we bought a SmartDriveDuo 30A Dual Channel Motor Driver, but we are experiencing problems with the PWM signal.
The vehicle consist of 2x 12V SLA batteries connected in series, a voltage regulator, Arduino UNO, the Dual Motor Driver and 2x 16.5A Brushed motors. This is how we connected it all together:
When we set the PWM signal to 150 or above, the motor driver run the motors perfectly, but when we set the PWM to below 150 the motors won't run. The DIP switch is set to 10110110. We have tried to power the arduino with an external battery with no luck.
The arduino test code is provided below:
Do you know how we can fix this?
Thanks in advance
