Security System using Arduino Bluetooth Camera

Arduino Bluetooth Camera

Arduino Bluetooth Camera

Arduino Bluetooth Camera is aimed to use the Camera shield with an ultrasonic to detect whether a stranger has entered our house. Then we capture a photo of him automatically once he gets into the area of the ultrasonic wave.

Of course, many security systems nowadays use open source hardware where you can develop your own security application according to your needs.

Thanks to Arduino platform and its based open source shields, you can now easily make your security systems which involve some security monitoring tools like alarm, laser, motion, distance, and camera.

Surely, the last one is the most important and popular one used almost in every security system. That’s because it’s the only way to recognize the penetration of the security from a stranger. And also it knows exactly who did that by capturing a photo of him.

In this tutorial, we are going to use Arduino Bluetooth Camera with the help of an ultrasonic to detect whether a stranger has entered our house and capture a photo of him automatically once he gets into the area of the ultrasonic wave.


Let’s talk about the idea behind the Security System using Arduino Bluetooth Camera …



The idea behind the Arduino Bluetooth Camera is to use 1Sheeld board with Arduino and the camera shield from the 1Sheeld App.

Simply, you will connect the App to the 1Sheeld via Bluetooth and hence we have an Arduino Bluetooth Camera!

This camera is ready to capture photos and store them into phones storage by one line of Arduino code!

We will also use the ultrasonic sensor with an obstacle in front of it on a certain distance (say 100 cm). Once anything comes in front of the ultrasonic sensor within the range of 10 cm or less, the system will consider this as a penetration.

Once a stranger has entered the house, the system turns on an alarm which is another shield (Buzzer Shield). Then the system captures a photo instantly to this stranger and saves it in the phone.


Getting started:

If this is your first time to deal with 1Sheeld or you want to learn more about it, I recommend checking this quick and easy getting started tutorial.

And if you haven’t tried ultrasonic before, I recommend checking this quick video.

Now, after you’ve become a little bit familiar with 1Sheeld, let’s start!


Step 1: Hardware components for the Arduino Bluetooth Camera Tutorial:

–       Arduino Uno.

–       1Sheeld+ board.

–       ultrasonic sensor HC-SR04.

–       4 * Male to female wires.

–       Arduino USB cable or 9-12v battery.

–       Android/iOS phone with 1Sheeld App installed on it.


Step 2: Software components:

Step 3: Connection and Schematic:

  • Plug the 1Sheeld board into your Arduino as this:

  • Connect the ultrasonic as illustrated below:

  • Switch the 1Sheeld power to operate on 5v (Not the 3.3v):

  • 1Sheeld have 2 modes: Uploading mode and Operating mode. You can switch between them using the switch close to the Digital pins and is called “UART SWITCH” on 1Sheeld and “SERIAL SWITCH” on 1Sheeld+.

Firstly, you slide the switch towards the “SWITCH” notation which turns the 1Sheeld board into the Uploading mode to let you upload the Arduino code.

Secondly, after you finish uploading the code, slide the switch towards the “UART” notation (or “SERIAL” at 1Sheeld+ board) which turns the 1Sheeld board into the Operating mode to communicate with your smartphone 1Sheeld App.

  • Finally, connect the Arduino via your PC using Arduino USB cable.


Step 4: Code:

I would recommend checking the Arduino Camera Shield documentation to know more about the Arduino Camera Shield functionalities and how to use them.

Now, switch the 1Sheeld board to the Uploading mode, upload this code:

Then, Switch the 1Sheeld board to the Operating mode then open the 1Sheeld app and connect it to the 1Sheeld board via Bluetooth.


Step 5: Run it:

Firstly, select the Camera, Buzzer, Terminal and Text-to-speech shields from the shields list.

I have used a 3D printed ship figure as a stranger. Once the ship cut the ultrasonic sensor range of 10 cm, the phone made a buzzer sound. Then it took a picture to the ship. Finally, the phone tells me with its speaker that a stranger has entered my house .. pretty cool, isn’t it 🙂

The ship photo was taken and stored:

Now we have done with this security system using the Arduino Bluetooth Camera.

You can add your own extra code lines to add more security warning features like what I mentioned at the beginning of this tutorial.

Hope you enjoyed this Arduino Bluetooth Camera tutorial!
