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 ...

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 ...

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 ...

「micro:bitとキットでマイコン制御」では、micro:bit V2と市販のセンサーキットの「KEYESTUDIO 37センサースターターキット micro:bit V2付」を使って組み込み技術に必要なマイコン制御の基本を学習します。 【第16回】：第1回の記事で準備した実習環境に、PIR ...

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 ...
