Raspberry Pi Pico-Controlled Automatic Golf Tee System with PIR Sensor and H-Bridge Motor Driver

Image of AutoTee: A project utilizing pi manual in a practical application

This circuit is designed for an automatic golf tee system controlled by a Raspberry Pi Pico microcontroller. It features a PIR sensor to detect the presence of a golf ball, three pushbuttons for user input to raise the tee, and adjust the height up or down. The system uses an H-bridge motor driver to control a linear actuator that adjusts the tee's height, with a buck converter stepping down voltage from a 12V power supply to a lower voltage suitable for the Raspberry Pi Pico and other components.
