arduino laser alarm – cheap Multi functional!

Hello world! I created a little arduino laser alarm from a laser Emitter and a Laser receiver.
I used the ky-008 laser and the laser receiver i used is called ky-008-2 on my website.
Officially it is not called ky-008-2 but any receiver will do.
The device is multi functional, i left some ideas in the code.

The code is just a basic code but from here you can build many cool stuff.
So with the code you got the basics to build a arduino laser alarm.

Schematic:
arduino laser alarm

Parts list:
Arduino Uno, (I used a copy which has 7 analog pins, a quality new model from 2016 called RobotDyn Uno.)
1 Channel relay ky-019
Laser Sender ky-008
Laser receiver ky-008-2 (i used ky-008-2 on my website as product code, i dont know the official code)
buzzer
7 color led ky-034
A set of Jumper wires. MM / FF / FM
A power cable and a lamp fitting + lamp connected to the relay (optional)

Code:

Good luck building your arduino laser alarm.
