Door Security System Using Arduino
INTRODUCTION:
In this project, we will make the Security Door System which is based on Arduino. This digital code lock can protect your home or your locker. The door will only open when the correct password was entered, and after some time it will close automatically. The main part of this project was Arduino which takes all the control like it takes the password from the keypad and shows it on the LCD if the password was correct then it allows the motor to run, and the door opened.
COMPONENTS THAT ARE USED:
- Arduino (Simulino UNO)
- LM016L (LCD 16X2)
- Motor-PWMSERVO
- Phone Keypad
First of all, we can connect the keypad rows A, B, C, and D with the Arduino pins 0, 1, 2, and 3 and columns with the Arduino pins 4, 5, and 6. After this, we connect the servo motor to the Arduino pin 9 and the other connects with the ground and the 5v (pin) on the Arduino board. In the end, we connect the LCD pins D7, D6, D5, and D4 to the Arduino pins A0, A1, A2, and A3, and connect the LCS pins E and RS to the Arduino pins A4 and A5. Connect the LCD in VSS and RW to the ground.
