This project uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer. This code ...

const int pirPin2 = 5; // Digital pin connected to the second PIR sensor int pirState1 = digitalRead(pirPin1); // Read the state of the first sensor int pirState2 = digitalRead(pirPin2); // Read the ...
