Hey friends welcome back today in this Instructable i will show you how to Make Tripwire security Alarm using Arduino.
A tripwire is one of the most basic ways to set up a very simple security system. You cross a line across a pathway. Whenever someone walks through the beam, the buzzer alarm activate. This project is very simple to build since we won't have to modify any parts.

I provided a image with all pins tagged to make things easier for you.
Plug our Buzzer into GND and Pin D8 of the Arduino.
The LDR will go into GND and Pin D2 of the Arduino.

Mount the Laser Pointer and the Alarm Circuit to Form a Single Beam Tripwire
The simplest way to set up your alarm is as a single beam tripwire. In this configuration the laser pointer is mounted to one side of the walk way and the alarm circuit is mounted to the other. For the tripwire to work, the laser pointer needs to be constantly on. The easiest way to accomplish this is by tightly wrapping a piece of tape around the button.
