Motor

Introduction

In this project, we will learn how to use the Fusion HAT+ to control a DC motor, making it rotate clockwise and counterclockwise.

Circuit Diagram

The circuit diagram below shows the connections required to control the motor.

Code

The following Python code controls the motor’s rotation direction and timing:

#!/usr/bin/env python3
# Import sleep function to pause execution
from time import sleep
# Import Motor class from the fusion_hat.motor module
from fusion_hat.motor import Motor

# Create a Motor object for motor port 'M0'
# is_reversed=True means the motor direction is inverted
motor = Motor('M0', is_reversed=True)

try:
   # Loop forever
   while True:
      motor.power(0)       # Stop the motor
      sleep(0.5)           # Wait 0.5 seconds

      motor.power(-50)     # Run the motor at -50% power
      sleep(1)             # Run for 1 second

      motor.power(0)       # Stop again
      sleep(0.5)           # Wait 0.5 seconds

      motor.power(75)      # Run the motor at 75% power
      sleep(1)             # Run for 1 second

finally:
   motor.stop()             # Ensure the motor is stopped on exit
   sleep(.1)                # Short delay for safety
