To connect the servo motor with the Arduino, use digital pin D9 of Arduino to output the PWM pin of the servo motor.
Connect all seven pins of the keypad to analog pins D1 ~ D7 of Arduino. For connecting the keypad with the Arduino we are using digital pins D1 to D7. You can use the Fritzing Software to draw the schematic.įirst of all, we will make a connection to the 4×3 Keypad. The circuit or the schematic of Password Based Door Lock Security System is fairly simple. You can purchase all these components from Amazon at affordable price. You can check one of our previous security system project: RFID RC522 Based Security Systemįollows are the list of components that you need for this project. Servo motor is used for opening the gate while rotating and LCD is used for displaying status or messages on it. The keypad is used for taking the password. Arduino controls the complete processes like taking a password from the keypad module, comparing passwords, driving buzzer, rotating servo motor, and sending status to the LCD display. The circuit of this project is very simple which contains Arduino, keypad module, buzzer, Servo Motor, and LCD. It will open your door only when the right password is entered. So a digital code lock can secure your home or locker easily. As thefts are increasing day by day security is becoming a major concern nowadays. In this project, we will learn how to make the Password-Based Security System Using Arduino & Keypad.
