Project description

My arduino project is a security system for home security, which gives subtle warnings when the house is about to be robbed or intruded.

Nowadays, everybody has security cameras and other powerful security systems installed in their homes. And I always wanted to know how they might have worked, so when there was a learning opportunity I thought to give the security system a try. 

Firstly, I started with understanding the concept of different sensors and how might I use them. Read through the documentation and then started to develop the circuit. Installing sensors and solutions one by one. Then started to write the code.

Code was not that difficult to write. The first problem I was facing was reading through the sensor values. It was difficult to know what value was sensor proving when attached to the computer. Another problem that I faced was to know how the tilt sensor worked because the buzzer was continuously making sounds. For reading the sensor value I started with referring to the serial monitor and also read the document API and for tilt sensor, I read through some projects in the Arduino book.

After putting circuit together, I tried implementing it on a box.

But when I attracted the breadboard to the box, the circuit broke. So I dismantled the board from the model and fixed it again.

Video description

The video shows how the system is working. It includes output result and input feed from sensors. The input from sensor is taken individually as well as together. One when the board is tilted and another kind when infrared sensor records some human moment. These input are recorded and output is shown through led light and sound.

Summary

Writhing code was easy, after thinking through the concept.

Wiring the Arduino motherboard and breadboard was challenging and fun.

Read all about functions of sensors and electrical components on the internet. 

The project was working as expected.
