Introduction: Arduino - ALARM STROBE With Sound Using Arduino Nano.

Picture of Arduino - ALARM STROBE With Sound Using Arduino 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, 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? follow the link for the schematic, Code & Parts list.

On the bottom of the 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.

Step 1: Schematic, Code & Parts List.

Picture of Schematic, Code & Parts List.

Just wire it up like the schematic put it on a breadboard to test first & then solder it onto a Prototype PCB Board and cut it so it fits into your Alarm Strobe. It should work after uploading Make sure you ADD the short pins of the LEDS to ground.

Parts list.

  • Arduino Nano.
  • 6 Leds. (Short pin on led is ground.)
  • PCB ProtoType Board (I used 5x7 cm)
  • Jumper wires set MM/FF/MF
  • 6 Resistors (Value is up to you, I did not use them!)
  • Buzzer.
  • 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 Alarm Strobe now!

I accidentilly uploaded the video instead of the code. make sure to use some resistors between the leds!
