Hello friends, in this project, we will learn, how to make security alarm by using Pir sensor and Arduino nano. I set 10 second time delay when system turn ON. After 10 second motion sensor detects motion, it sent signal to arduino nano and arduino nano turn ON the alarm for three seconds. You can change this time from code.

Supplies

Connect BD139 Transistor to Arduino
