Physical Computing Project Proposal

Introduction

This is the final idea for our group. We have decided on creating project called ‘MyPod’ which is music player system that allows user to play their playlist by scan their finger. If their finger saved into the system than they can play their playlist and green LED will turn on and if the fingerprint doesn’t stored than music won’t play and red LED’s will turn on.

The main reason that we are doing this project is because we considering people in need and how we could help them on a big scale and this system give users more power and listening options in a traditional format. MyPod recognise every individual playlist for example if I put my hand in fingerprint scanner it recognise my music playlist will start playing straightaway and if someone else want to change all they have to do is to put their hand on the fingerprint scanner and their music playlist will start playing. This system is easy to use and navigate as it allows user to sync multiple playlists from myPod while the systems displays song title or playlist name that the user listening to.

Project Requirement

Input no 1

Fingerprint scanner:- Allows users to scanner their fingers in order to play the music.

Input no 2

Push Button:- This is used to control or to stop the music.

Output

LCD:- display two rows with up to 16 characters on each row. I decide to solder wires to it, and I choose to solder the connectors to the back so I could press the LCD display on the breadboard.
Speaker:- use of a Piezo Speaker in order to play the music or song.It produces notes with a certain frequency and it has two pins, one pin I am going to connect to GND and the other to pin 8.
LED:- displaying the program status to the user for example if your finger saved into the system than you can play the playlist and green LED will turn on and if the fingerprint doesn’t stored than music won’t play and red LED’s will turn on. The long pin of the LED is connected to +5v, and the others are connected to a resistor of 270 Ohms each one.

Suitable Housing or On Screen Display

On screen display:- On-screen display is using processing to show audio visual synth.

Components

Potentiometer:- I used the potentiometer to set the contrast of the display so I turned the potentiometer to slowly from left to right in order to adjust the contrast.This will also allow us to control the speed of the music just rotating it and it gives values between 0-1023.

Resistors:- are a small component which is designed to provide a specific amount of resistance in an electronic circuit because resistance is an essential element of nearly every electronic circuit,

Arduino UNO and Arduino IDE

It is an open source electronics prototyping platform, easy to use hardware and software.
Its environment allows us to program the micro-controller of the Arduino UNO.

Various Wires:- We will use more wires with different colours in order to recognise which wire connect breadboard and arduino uno.

1 x Connector (16 pins)
1x Speaker
1x 3D box for suitable housing AND/OR an on-screen display

Project Aims & Outcomes

The aims of our project is to operate within personalise system because using fingerprints for identification and recognition is the oldest use of biometrics but, there are many reasons why the use of fingerprints is the most common form. For example, the person to be identified is required to be physically present at the time of identification.

Outcomes of this system is to play music in the playlist by scan the finger individually and everyone’s taste in music is different so no matter what music you listen.Future improvements to be carried out are:-

To have wake up function
Integrate more inputs or sensor to activate finger scanning.
Use actuator for an application

What are you investigating?

We are investigating a way to personalise music by combining a fingerprint scanner, LCD and some leds to store music and play the playlist depending on which finger is placed on the reader.

What challenges did you overcome?

A challenge we overcame was we had another idea which was a fingerprint lock device but it wasn’t interesting enough so we had to change it.

What inspired you?

The thing that inspire us to do this project is because we considering people in need and how we could help them on a big scale. Even though people are more likely want to use new products so if our products meet their needs and match their values and we can find information about a person’s needs and values by carrying out research.

The main reason that inspire us is when we think about the challenges we face and identify possibly solution that we came up with.

Diagram:- Below you can also see diagram both parts for breadboard view and schematic view.

Suitable housing AND/OR an on-screen display

As the part of the project, I created 3D box in the lab for suitable housing AND/OR an on-screen display, as you can see below images it displays the LCD and fingerprint scanner in the box at the same time. The main reason I did this is to see the project material in the box to be organised and display everything. I used http://www.thingiverse.com/thing:420860 site to design customisable sorting box and I used 3D printing which takes more than five a hours to complete the initial.
