Transcript of FYP : ELECTRONIC MAILBOX

Introduction
Equipped with LED, LCD & Buzzer.
Main function : An indicator when letter is arrived.
Advantages : - Prevent overdue bills. - Better awareness when receiving new mails. - Help to ease user.
Problem Statements
The distance between normal mailbox and home. - Changes of weather.
The time taken for the letter to be received. - Busy with daily routines.
So, the normal set of mailbox is modified.
Scope of Work
1. Figure out the project title - brainstorming method.
2. Make a list of the required components.
3. Sketch the circuit diagram.
4. Create circuit diagram using PROTEUS software.
5. Print the circuit on circuit board.
6. Place components on the PCB and solder them.
7. Do connectivity test.
8. Test the device for the buzzer, LED, LCD to function properly.
9. Place the device in a casing.
Methodology
Final Year Project :
Electronic Mailbox

Flowchart of the Circuit
Objectives
To design a mailbox that gives signal to people.
To update owner with new arrival of mail.
Expected Result
Upon completing this project, the electronic mailbox will give a signal to the users and this will help to ease them. Other than that, problems that people are having such as late payment of bills will decrease drastically since this project helps the people to become more aware when their mailbox is filled with new letter.
