added PWM ability #2

Closed neumann-d closed 7 years ago

neumann-d commented 7 years ago

uses RPi.GPIO.PWM:

PWM frequency is globally set in _MOTORS dictionary (50 Hz by default), but can be accessed/changed with getter/setter function
PWM duty cycle is used for speed control (0-100), additional speed argument for run_dc_motors function

Hi, thank you for adding PWM support. I will test it and then I will merge it. Could you please also modify example file to show others how to use it. Thank you.

neumann-d commented 7 years ago

Hi @lipoja , I added few lines to the example code.

Thank you for the code, I did some modification of the code. The PWM it's working. Just find the right frequency to run the motors :]
