Introduction: Simple Arduino Laser Alarm
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.
