Tutorial Contents

The project is an embedded system consisting of a microcontroller, motion detector and LCD which can control the Buzzer depending on the presence of an impingement within six meters of range. By using this procedure valuable properties and homes can be secured as the Buzzer is triggered when there is an impingement.

• Steps

1 . Gather all the components

2 . Connect keypad to Arduino board

3 . Connect PIR motion detector to Arduino board

Pin 1: 5V VCC in Red
Pin 2: output in Yellow
Pin 3: GND in black

4 . Connect Buzzer to Arduino board

Pin 1: 5V VCC in Red
Pin 2: GND in black

5 . Connect LCD to Arduino board

Complete system connection

6 . Programming

• Keypad library setup.

i. Download the keypad library here

ii. Extract the keypad library

iii. Install the keypad library into Arduino IDE by moving extracted folder into Arduino\libraries

iv. Restart your Arduino IDE

• connect the set up to your computer

• open the Arduino IDE, go to Tools>board>select Arduino Uno

• copy my code here and paste into the IDE

The program code does the following:

1. It initializes the Microcontrollers
2. It initializes the Keypad
3. It asks you to Input New Password
4. It asks you to confirm Password
5. It initializes the Sensor PIR
6. It initializes the LCD
7. It Setups a Continuous loop
8. It reads data from Sensor

• Condition 1

-. Is there any motion?

A. If YES: It initiates a buzzer sound

B. If No: It continues the Loop

• Condition 2

-. Is Correct password inserted?

A. If YES: It deactivates buzzer

B. If No: It continues the Loop

Loop continues to 1

• save and compile the code

• this will check for errors in the code

• If there are no error found, upload unto the Arduino board

7 . Testing

Having followed all the steps rightly, power on the project. It will display as shown and it will ask for new user password.
