Arduino ALARM STROBE With Sound using Nano

Hello world! I had a broken alarm strobe bought in china and i thought today i am going to fix it with a Arduino Nano and make a Arduino ALARM STROBE, Now it also has sound. I removed the original PCB because some copper parts fell off, so i made my own PCB for the leds with a prototype PCB Board. Wanna build it yourself?
I did not use resistors but you should use some resistors on the leds.

On the bottom of the Arduino ALARM STROBE enclosure i placed 2 wires for GND & VIN. I connected the Red wire to VIN & the Black to GND on the arduino Nano, and connected a 12v Adapter.

It does not make allot of sound, but i want to use it for intruder detection and add a PIR sensor to it so this small alarm triggers and i know something is moving in front of my door.


Parts list:
Arduino Nano.
6 Leds. (Short pin on led is ground.)
PCB ProtoType Board (I used 5×7 cm)
Jumper wires set MM/FF/MF
6 Resistors (Value is up to you, I did not use them!)
Breadboard (optional)
alarm strobe enclosure, (I used a broken one you can buy it here) very cheap!
9 Volt to 12 Volt Adapter.

Good luck! You Can change Tones in the code! And program your Arduino ALARM STROBE!
