CHAPTER 1
1.1.Background
Money is a tool used for make buying and selling transactions and has been used
by all humans in every corner of the world. This is certain making money important thing
for everyone, even for people with disabilities such as blind people. The limitations of the
blind in terms of seeing are problems in terms of communication so they just rely on the
sense of touch and listener. Weakness of blind people in seeing and identifying money
can be causing money to be exchanged, wrong take, or even deceived when buying and
selling. Referring to that problem they need for tools that can facilitate blind people to
identify the face value of money.
From problem above i make a device that can help blind people to detect the face
value of money paper. This tool uses a TCS3200-DB color sensor to detect the color of
the banknote, then by The microcontroller is converted to RGB data and outputs in the
form of sound.
1.2.Research Problem
a) How to make money color detectors for blind people ?
b) How does the color detector for blind people work?
c) How can this tool be of benefit for blind people?
1.3.Significance of the problem
Detection of paper currency is very helpful for people, especially people who are
blind. Because money is a means of payment for buying and selling transactions.
Why is money important? Because money is the only means of payment in
Indonesia. all transactions use money.
1.4.Scope and Limitation
In this discussion only discusses the paper money. Because the sensor is used
specifically to handle money that has a variety of colors, like paper money.
1.5.Definition of key terms
A. Blind people
Blind people is a general term used for the condition of someone who has a
disturbance or obstacle in their sense of sight. Based on the level of impairment Blind
people are divided into two, namely total blindness and those who still have vision
(Low Visioan). Aids for mobility for the blind using a special stick, which is white with
a horizontal red line. As a result of the loss / decrease in the function of the sense of
sight, the blind try to maximize the function of the other senses such as, touch, smell,
hearing, and so forth so that not a few blind people who have extraordinary abilities
such as in music or science
B. Paper Money
Paper money is money made from special paper material in which special pictures
and stamps are printed, and are used aslegal tender.
C. Colour Sensor
TCS230 color sensor is a color sensor that is often used in microcontroller
applications for the detection of an object object or color of the objet on the monitor.
The TCS230 color sensor can also be used as a motion sensor, where the sensor detects
the movement of an object based on the color change received by the sensor

3.1.2 List and Explain the Part
3.1.2.1 Arduino Uno
Arduino Uno is single-board microcontroller that open source. Arduino has a
design to make a easy electronic user to make a something project. The hardware of
Arduino has Atmel AVR processor and the software of Arduino use programmable with C
language.

3.1.2.2 TCS 230 Color Sensor
TCS230 color sensor is a color sensor that is often used in microcontroller applications for
the detection of an object object or color of the objet on the monitor. The TCS230 color sensor can
also be used as a motion sensor, where the sensor detects the movement of an object based on the
color change received by the sensor. The TCS230 color sensor is basically a photo
diode array arranged in 8 × 8 array matrices with 16 photodiode configurations that
function as a red color filter, 16 photodiodes as blue filters and 16 photo diodes again without color
filters. TCS230 color sensor is a sensor packaged in 8 pin DIP chip with transparent front as a
place to receive the intensity of the colored light.

3.1.2.3 MP3 Player Module
Mini MP3 Player Module is a compact and inexpensive MP3 module can be directly connected to
the speaker. Module with battery power, speaker, keypad can be used alone, or through the serial port
control, as the Arduino UNO or any microcontroller with a serial port module. The module itself perfectly
integrated hardware decode MP3, WAV, WMA’s. While the software supports TF card driver to support
FAT16, FAT32 file system. Can be done through simple serial commands specified music player, as well
as how to play music and other functions, without the cumbersome underlying operating, easy to use,
stable and reliable.

From the block diagram above, it can be explained about the workings of the system above,
namely:
1. In this planning diagram, color is the parameter used in the money color detector for people
with visual impairment, therefore color as sensoring, so we use the TCS3200 color sensor as a
color sensor for this clothing. So that the output or the reading of the RGB color values will be
sent to the microcontroller for further processing. For the TCS3200's own supply, it will be from
the microcontroller.
2. Microcontroller where as a controller or controller of all activities that occur in the system. For
that we use atmega16 as a control. Microcontroller as a connector from the sensor into an
actuator, without a microcontroller certainly will not be able to regulate, control a system, except
using other methods such as embedded systems, microprocessors etc. For the supply of 5 volts
which will be connected to the sensor or actuator as well as the supply.
3. Supply, which is a component that is very influential in a system. Without a supply, it is
certain that the system is unable to run, even with various methods. So that supply is very
important. For this system, a 5 volt 4mA-20mA DC supply is used to run the microcontroller,
sensor and actuator.
4. Voice data storage, which later results from the reading of the Nand color sensor in the form
of sound, so voice data is needed. So we use the MP3 module as a medium, which will later be
stored on the SD card and can be directly connected to a headset to be listened to by the wearer.
Later we will make sound recordings that are named according to the color, so that later the
controller can call files that are on the SD card and issued as output.
5. Sound, where this is an output that will later be listened to by the user with the help of a
headset, so that the sound he hears is clearer and more flexible in the wearer's.
