Creating security or alarm systems using sensors like motion detectors or door/window switches is a practical way to enhance home security. In this example, we’ll build a basic security system using an Arduino, a PIR motion sensor, and a piezo buzzer. This system will trigger an alarm when motion is detected. Here’s how to create it:
Components you’ll need:
Arduino board (e.g., Arduino Uno) PIR motion sensor Piezo buzzer Breadboard and jumper wires Power supply for Arduino (e.g., a USB cable and adapter) Circuit Connections:
