The objective of this project is to learn how to create a motion sensor that triggers a red light and buzzer when it senses movement.
You can use this Arduino-controlled alarm to trigger a variety of outputs, such as lights, motors, or even a “welcome home” message when you approach your front door.
When this project is successfully built, the sensor will detect motion and trigger an alarm buzzer to sound and an LED to light up.
This is project 21 from the Arduino Project Handbook, V1 by Mark Geddes.
We built it on a WorkBench Project Development Kit from Phase Dock.
