Today I am sharing the Proteus simulation of my project, in which I have shown the working of three sensors with a single Arduino. These include a PIR sensor (digital), flame-detecting sensor (digital ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

int pirPin = 2; // PIR sensor output connected to pin 2 int ledPin = 13; // LED connected to pin 13 (or relay module) ...
