Inception
The aim of the project was tounderstand and execute practical skillsin electronics technology and to
introduce innovation to the productthat we were designing. Deriving ourthought process from simple radio
experiments, we decided to take achallenge ourselves with the workingof a MP3 player

Objective
We aimed to create a player withfluidity of interface and a robustdesign. We decided to combine science
with the real world market to have aproject that was not just onedimensional but had a market value
and could be used in everyday life

Variables
A robust project had to be one whichwould work in all environmentalconditions and situations without
breaking down or implying a lack ofattention to detail
Repeated usage of controls to ensure
that they continued to function welland the wires did not loosen.

Programming
An additional component of theproject, apart from the circuitry, was todesign and load the program into the
microprocessor.
We developed skills into computerlanguages of Java and C. Using the
software Arduino, we worked towardsa fluid interface without facingproblems of harming the components
and perfectly synchronize all the

Problems
We had to overcome a wide range ofproblems to complete the project suchas:
Prevent a high current through thecomponents and ensure adequateresistance in the circuit at all times
Ensure the circuit was complete andcorrectly wired using a CRO beforeloading the program.

Results
A survey was conducted betweendifferent areas of society to find outthe response to our project. We wanted
to test its durability and control andreleased it into our community. Weconducted our survey for a week to
identify any possibilities forimprovement. We will now show youthe various responses that wecompiled.

Further goals
We believe that projects are nevercomplete they are only due. Evenafter this exhibition we aim to work to
improve our project by making itsmaller and more user friendly.
