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 PWM signal on the control pin that is needed to make the motor go in the forward direction at the maximum speed

• duty_back = 6 # 6 min: This sets the duty cycle of the PWM signal on the control pin that is needed to make the motor go in the backward direction at the maximum speed

• PWM.start(motor1, duty_stop, 60.0): This sets the PWM signal...
