Create an Alarm System and Visitor Counter for Your Door Are you tired of guessing who's at your door? Do you want to know when someone is approaching or entering your home? With this DIY alarm system, you can create a secure entrance that alerts you to visitors. This project will guide you in building an easy-to-use visitor counter and alarm system using basic electronic components. Materials: * 1 x 16x2 LCD display * 1 x keypad (4x4) * 1 x Arduino Uno R3 board * Jumper wires * Breadboard Step 1: Connect the Components Connect the keypad to the Arduino board. The keypad will allow you to input a code to unlock the door. Next, connect the LCD display to the Arduino board. This will display the number of visitors who have entered your home. Step 2: Write the Code Write the code for the alarm system using the Arduino IDE. This will involve creating variables to store the visitor count and code entry. Use the keypad to input a code when someone approaches the door. If the correct code is entered, the LCD display will show the number of visitors who have entered your home. Step 3: Add the Visitor Counter Add a visitor counter that increments each time someone enters your home. This will be displayed on the LCD screen. To add the visitor counter, use a variable to store the count and increment it each time the code is entered correctly. Display this count on the LCD display. Step 4: Test the System Test the system by entering different codes and observing how it responds. Ensure that the correct number of visitors is displayed on the LCD screen. Tips and Variations: * Use a motion sensor to detect when someone approaches the door. * Add a camera to record video or take photos of visitors. * Program the system to send notifications to your phone or email when someone enters your home. With this DIY alarm system, you can create a secure entrance that alerts you to visitors. This project is perfect for homeowners who want to stay informed about who's at their door.
