Project Area of Specialization Cyber SecurityProject SummaryThe general operation of the system is whenever there is any person at the entrance doorbell should start ringing. Light focusing on the LDR determines whether a person is present or not. When there is any object at the entrance, LDR is in dark and buzzer starts ringing and the LED starts glowing. In addition to this, we can add Wi-Fi module, to upload the data into remote cloud, to access it from anywhere in the world.
You will need an Arduino Uno board to act as the brain of the system. And the microcontroller will be connected with a WiFi module to establish an internet connection. The system you are going to design will have an LDR (Light Dependent Resistor) which act as an Eye for the system. You will programme the microcontroller in such a way that not only the doorbell should ring, whenever you some person is standing in front of the door but also it should store the data regarding status of the doorbell etc., in the remote cloud simultaneously. You can also innovate the system further to send a notification to a user at any part of the world via sms or email.
- Arduino/Genuino Uno: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
- LDR (Light Dependent Resistor): An LDR can be called as variable resistor controlled by intensity of light. Whenever the LDR is in very low light, the resistance value of the LDR will be very high (in Mega Ohms). Similarly Whenever the LDR is under normal light the resistance value of the LDR will be very less comparatively (in order of 10^2 Ohms).
- 7805 IC: IC 7805 is an integrated circuit which can used as a voltage regulator. It is an electronic circuit that provides a stable DC voltage independent of the load current, temperature and AC line voltage variations. A voltage regulator may use a simple feed-forward design or may include negative feedback. Depending on the design, it may be used to regulate one or more AC or DC voltages.
In the World of Security, Automated security systems are emerging technologies these days, Electronic eye is also called Virtual eye which is an electronic device, which observes whoever coming and going continuously. Let us assume, a door bell that automatically rings when a person visit your home and it can also be used for providing security when any person is trying to enter into your home without your permission. Through this project you are going to build a unique system which automatically rings the doorbell when there is a person standing in front of the door.
Project Implementation Method- Initially, interface buzzer, LDR and Wi-Fi module to the Arduino board
- Now connect the supply voltage of 9v using battery
- Keep the LDR in light .You will see no sound is produced from the buzzer
- Similarly keep the LDR in dark, you can see buzzer starts ringing. LED connected to the buzzer also starts blinking
- As the intensity falling on the LDR increases sound produced by the buzzer increases
- The data about all of this will be sent to the cloud for storage and analysis

- Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
- Thingspeak : Also, you need to create an account in the ThinkSpeak IoT platform to integrate the system onto the cloud and store the data online
