Burglar Alarm with Arduino

Buzzer

Alphanumeric LCD, 16 x 2

Arduino UNO

PIR Sensor, 7 m

I recently moved into a shared apartment. And I was tired of my room-mate coming into my room when I was out because "He needed some-things!" But every time I asked him about it, he refused it straight away. So, I thought of using my knowledge to good use and I created a Burglar alarm. The alarm uses a PIR sensor to detect motion and as soon as there is motion, the Arduino sets off a buzzer. It also starts a timer and displays it on an LCD so I know exactly when he entered my room.The Full Project Details Can Be Found at:<a href="https://rocrafto.com/2020/04/20/how-to-use-a-pir-sensor-for-a-burglar-alarm/">How to Build A Burglar Alarm</a>
