What is Arduino alarm system?

Arduino Alarm System – Arduino Project Hub Arduino Alarm System © Apache-2.0 Arduino Uno alarm that detects movement, alerts when triggered, can be armed and disarmed via keypad and displays status on an LCD.

What should the Arduino do as it detects an intruder?

We define what the Arduino should do as it detects an intruder. Here, we are creating an alarm sound through a piezo buzzer. When the sensor detects an intruder, it triggers an alarm sound through the buzzer. The piezo buzzer is activated through the Arduino using PWM (pulse width modulation) signals.

How does a PIR motion sensor work with Arduino?

When the PIR motion sensor detects a person, it outputs a 5V signal to the Arduino and triggers an interrupt. We define what the Arduino should do as it detects an intruder. Here, we are creating an alarm sound through a piezo buzzer. When the sensor detects an intruder, it triggers an alarm sound through the buzzer.

How do I connect a motion sensor to an Arduino?

Connect the VCC and GND on the sensor to the Arduino’s 5V and GND pins. Next, connect the output signal pin on the motion sensor to the Arduino’s digital pin 2 (interrupt pin 0).

Will digital alarm clock work on Arduino Mega Board?

Digital Alarm Clock based on Arduino MEGA board and 2×16 LCD display is the topic of this post. Similar design based on Raspberry Pi can be found at this link. For PIC16F877 version click here. This design should also work on Arduino UNO or any other compatible boards.

How do I connect a LCD to an Arduino?

Pin 1 on the LCD to ground on the Arduino. Pin 2 on the LCD to 5V on the Arduino. Pin 3 on the LCD to the middle pin on the 10K potentiometer. Pin 4 on the LCD to digital pin 2 on the Arduino. Pin 5 on the LCD to the ground of Arduino. This will put the LCD in read mode. Pin 6 on the LCD to the pin 3 of Arduino.

How do I set the beeping time on my Arduino?

The beeping time in our code is 2 minutes, but you can increase it as much you want. The time and date will also be displayed on the LCD. Pin 1 on the LCD to ground on the Arduino. Pin 2 on the LCD to 5V on the Arduino. Pin 3 on the LCD to the middle pin on the 10K potentiometer.
