Video 19: Simple Control of Servo From Raspberry Pi¶

Learn how to control a servo motor with a Raspberry Pi as Paul McQuarter guides you through the setup, coding, and testing process.

  1. Hardware setup: Paul demonstrates the correct wiring and alignment of the servo motor with the Raspberry Pi.

  2. Power considerations: He explains the importance of using an external power supply for larger servos to avoid damaging the Raspberry Pi.

  3. PWM basics: Understand how Pulse Width Modulation (PWM) controls the servo motor’s position by adjusting the duty cycle of the PWM signal.

  4. Python code implementation: Walk through the Python code to set up and control the servo motor using GPIO pins.

  5. Testing and calibration: Learn how to test and calibrate the servo motor’s range of motion by inputting different PWM percentages.

  6. Error handling: Discover how to handle errors and ensure proper cleanup of GPIO pins using try-except blocks in Python.
