Program to control DC motors using the BeagleBone Black

Now that you've connected your motor, here is a simple Python program to control one of the motors:

Let's look at the details. Here are the individual command statements:

• #!/usr/bin/python: As noted earlier, this command sets up the program to be executed without invoking Python
• import Adafruit_BBIO.PWM as PWM: This library is used to communicate with the GPIO pins
• motor1 = "P8_13": This sets the motor to PWM control P8_13—the 13th pin on the 8th connector
• duty_stop = 9: This sets the duty cycle of the PWM that is needed to stop the motor
• duty_forward = 12 # 12 max: This sets the duty cycle of the ...
