Introduction: Cheap DIY LASER ALARM - Multi Functional!
Hello peepz, I created a little 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.
This device is multi functional, i left some ideas in the code.
Check the next step for the schematic and 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.
Step 1: The Schematic, Parts List and Code.
Just wire it up like the schematic and it should work after uploading the code.
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)
Succes!
Create something cool and show me in the comments!
