I created an automatic door opener using a Micro:bit, which mimics the functionality of modern smart doors. This system eliminates the need for manual operation by detecting when someone is near and automatically opening the door. This project is both convenient and fun, providing a glimpse into smart home automation technology.

To make this project, I used a Micro:bit as the core controller. The device is programmed to sense motion or proximity, which serves as a trigger for the door to open. A USB cable connects the Micro:bit to a computer for coding and power. By leveraging sensors or logic, the Micro:bit can interact with external components like servos or motors that move the door.

Here’s how it works: The program uses a condition to detect a specific input, like motion or a signal. When the input is received, the Micro:bit sends a command to activate the door’s motor, opening it smoothly. If no motion is detected for a set time, the door automatically closes. This system replicates the user-friendly functionality found in commercial automatic doors and is an excellent way to learn about automation and embedded systems.
