A Tiny Alarm System Using a Super Tiny Arduino Compatible Board!

Hello, today we are going to make a tiny cool project. We are going to build a tiny alarm device that measures the distance between itself and an object in front of it. And when the object moves past a set distance, the device will notify you with a loud buzzer noise.
To make a tiny alarm device, we need tiny components, that is why we used PICO as our microcontroller, as it fulfills our needs while being very small in size. We also used commonly used components to read the distance and give a signal to the buzzer. This project will take you around 45 minutes to finish, if you chose to use the provided code.”
