Introduction: Arduino Laser Security Shield

*** I AM THIRTEEN. I REALLY ENJOY PUTTING TOGETHER THESE INSTRUCTABLES. PLEASE SHOW SUPPORT BY VOTING FOR ME IN THE LASER CUTTER CONTEST - https://www.instructables.com/contest/epilog3/***

I started thinking about this project a couple of months ago now. A laser tripwire that can log when the beam is broken and has the ability to take a picture when the beam is broken. Perfect for the bedroom intruder and what's more protecting food! So I had a look around online only to find nothing. So I suppose this is why it is now released as an open source project. If you need any help with anything feel free to contact me,

This Tutorial Is Also Here With All Images And Schematics - http://www.bitline.co.uk/index.php?cID=78

Step 1: Step 1 - Parts That You Will Need

All of the parts for this project should be readily available from hardware and small electronics stores. Me, myself, living in the heart of Somerset I can pretty much guarantee they are available pretty much any where. However if you do have trouble finding the parts then a kit excluding the arduino is for sale here .

Right, Parts Needed:

1x Arduino

1 x LDR - Light diode resistor
1 x 6V Buzzer (Five volts if possible)
1 x breadboard or PCB
1 x 10k Resistors
4 x 560 ohm Resistors
3 x Leds - Preferably Red, Green and Yellow.


PLEASE IGNORE THE RESISTOR DIAGRAM BELOW. YOU ONLY REQUIRE ONE 10K RESISTOR AND INSTEAD FOUR 560 OHM RESISTORS.




Step 2: Time to Get Wiring

If you cannot see the images here for any reasons I have made them available here - http://www.bitline.co.uk/index.php?cID=78

PLEASE NOTE THAT ONE OF THE SCHEMATICS BELOW HAS WIRING INSTRUCTIONS ON.

Below you can see the schematics. If you have a problem reading these then, please, contact me.

Step 3: Downloading the Code Onto the Arduino

All code is available here - http://www.bitline.co.uk/index.php?cID=78

Please be aware that this was written for the Arduino Uno

Step 4: Complete

Great! We have built it. 


Yet again I would like to ask you to vote for me in the laser cutter competition found here - https://www.instructables.com/contest/epilog3/


Many thanks,
Jordan

Awesome Jordan! It would be really cool to see it in action. Think you could put up a video of that?

Sure! Give me a day or two and I will see what I can do. In the mean time there is a poorly made video of it here - http://www.youtube.com/bitlineelectronics - Please be aware that on one of the videos I reversed the code so that it would only go off it was in contact with light. The buzzer really packs a punch.

Hello, there I would like to remake your project using my newly acquired arduino.
I tried to locate you code using the website you've provided, but nothing was there. Can you possibly post your code here. I new to arduino and I have no idea yet to program this project. Thank you.

Sir
Its "Light Dependent Resistor" not "Light Diode Resistor" as Diode is something else
