In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

SmartGate is an Arduino-based automatic door opening system that uses a PIR (Passive Infrared) motion sensor to detect human presence and automatically open or close a door via a servo motor. This ...

Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...

This ESP32 motion sensor project pairs the HC-SR501 PIR sensor with Arduino to build a real-time motion detection system with a live web dashboard. It works as a home automation trigger or as a first ...

定年後の趣味として諸先輩方の製作記事を読み、電子工作を始めました。子供の頃に戻ったようで楽しく気が付けば、5年が過ぎていました。 最初に手掛けたのが、当時流行っていたオンプレミスIoTでした。 現在では、IoTという言葉はすっかり影を潜めて ...
