Parts:

Arduino (any board)

breadboard

laser receiver module

laser module

LED (any colour /color)

buzzer

jumper wires

Things you may want to add:

siren light

relay to control any thing

mirrors

Step 1: Wiring Up

First make sure your Arduino is turned OFF.

start with power to breadboard, laser module, laser receiver module, buzzer (short wire) and LED (short wire) plugged into ground / - / GND and 5v / +

Arduino inputs and outputs:

Pin 13 to "s" (signal) pin to the laser module

Pin 12 to the LED (long wire)

Pin 11 to the buzzer (long wire)

Step 2: Upload Code to the Arduino

Note: In the code I have written the alarm will sound for 3 seconds.

Plug your Arduino into your computer

select what type of board it is: Tools, Board,

the Arduinos COM port: Tools, serial port

and finally upload (ctrl-u)

Step 3: Thing Your May Want to Add

Siren light:

Take your light apart and remove all unneeded things inside and glue an LED in and plug the wires into were it was before. ______________________________________________________________________________________________

Relay:

Plug your relay into GND, 5v and Pin11 (you will need to add this into the code)

______________________________________________________________________________________________

Mirrors:

Place the laser some were then place a mirror were the laser shines and do this till you like it, But make sure to aim it at the laser receiver module.

Step 4: Setup

Place the laser some were and aim it at the laser receiver module.

Turn on your Arduino and your done.
