A home security system using a PIR (Passive Infrared) motion sensor connected to an Arduino. The system detects motion and triggers both audible (buzzer) and visual (LED) alerts. The project is ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

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 ...

Furthermore, the vacant solder pads near the three-pin interface header is for mounting a light-dependent resistor (LDR/CdS cell). This, if added, causes the detector to be operational only when the ...

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 ...

Abstract: This article initiates photovoltaic (PV) modeling and simulates implementation of the maximum power point tracking (MPPT) algorithm for solar energy panels using an Arduino UNO R3 board in ...
