This project uses a PIR (Passive Infrared) sensor to detect motion and displays the status on an I2C Liquid Crystal Display (LCD). When motion is detected, a message is shown on the LCD and printed to ...

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 ...

This project is an Arduino-based embedded system that monitors environmental temperature and human motion, displaying real-time information on a 16x2 I2C LCD. It is designed to demonstrate basic ...

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 ...

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...

マイクロコントローラーや安価なシングルボード・コンピューターを使ったすばらしいDIYプロジェクトが多数報告されています。しかし、Arduino、Raspberry Pi、BeagleBone...どのボードを選べばいいのか悩みますよね？今回は3つの人気ボード、Arduino Uno、Raspberry Pi ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...
