Overview of Arduino Door Security System Project
The Arduino Door Security System Project is an innovative way to secure your home or office. This project utilizes an Infrared (IR) Sensor to detect any object in front of the sensor. When the sensor detects an object, it will trigger a small buzzer to sound an alarm. This project is relatively simple to construct and requires minimal components, such as an Arduino board, an IR Sensor, a small buzzer, and a power supply.
Connecting Components
The first step in constructing the Arduino Door Security System Project is to connect the components. The 5V and ground of the sensor module should be connected to the Arduino board’s 5V and ground. The digital signal pin should be connected to the Arduino board’s digital pin 2. The negative terminal of the buzzer should be connected to the ground, and the positive terminal should be connected to the Arduino board’s digital pin 11. It is important to note that the digital pin 11 should be a Pulse Width Modulation (PWM) pin in order to control the sound of the buzzer.
Writing the Code
The next step in constructing the Arduino Door Security System Project is to write the code. The code should begin by declaring the sensor and buzzer components in the declaration section. In the setup function, the modes of both components should be set to input and output, respectively. In the loop function, the value from the sensor should be read and, if the value is low, the buzzer should be turned on.
Testing the Project
Once the components have been connected and the code has been written, the Arduino Door Security System Project is ready to be tested. To test the project, place an object in front of the IR Sensor. If the buzzer sounds, the project has been successfully constructed.
Overview of Arduino Door Security System Project
The Arduino Door Security System Project is a simple and effective way to secure a home or office. It utilizes an infrared (IR) sensor to detect motion and sound an alarm when an intruder is detected. The system consists of an Arduino microcontroller, an IR sensor, and a buzzer. The Arduino microcontroller is programmed to read the sensor pin and compare the state of the sensor. If the sensor output is high, the buzzer is activated and a continuous sound is produced. To create a more effective sound, the Arduino microcontroller uses an analog write function to create a pulse-width modulation (PWM) signal of different voltages. If the sensor state is low, the buzzer is switched off. The complete unit is then fixed on the door and powered up using an external 9V battery. When someone tries to open the door, the buzzer will start making the sound.
Components Required
The components required for the Arduino Door Security System Project are an Arduino microcontroller, an IR sensor, a buzzer, and a 9V battery. The Arduino microcontroller is used to read the sensor pin and compare the state of the sensor. The IR sensor is used to detect motion and sound an alarm when an intruder is detected. The buzzer is used to create a continuous sound when the sensor output is high. The 9V battery is used to power up the complete unit.

}
Void loop() {
Int sensorState = digitalRead(sensorPin); // Read sensor pin
If (sensorState == HIGH) { // If sensor output is high
DigitalWrite(buzzerPin, HIGH); // Activate buzzer
AnalogWrite(buzzerPin, 255); // Create PWM signal of different voltages
Delay(500); // Delay
AnalogWrite(buzzerPin, 0); // Create PWM signal of less voltage
}
Else { // If sensor output is low
DigitalWrite(buzzerPin, LOW); // Deactivate buzzer
