Introduction: Smart Home Floor Register (Floor Vents)

By

My smart floor register is a DIY project designed to optimize home heating. It uses a Raspberry Pi Pico 2W, a temperature sensor, and a stepper motor to automatically open or close floor vents based on room temperature or a schedule. This setup helps save energy, improve comfort, and bring smart home functionality to traditional heating systems—all at an affordable cost.
