Nominal of Money and Colour Detector for the Blind People

摘要

Blind people often face a detection to identify the colour object. One of important of inability from the blind is to identify a nominal of money. It is very likely occurrence of undesirable things, such us as the possibility of exchanged money, or even act of fraud. It is necessary to design an equipment that allows for detecting a colour and a nominal of money. This tool is designed using TCS3200, RGB LED, LDR as the sensors, Arduino Nano as the controller and speaker. The sensors will detect the colour of the money, then sensors will transforms the colour into analog data and Arduino Nano will process this analog data into a digital data. Arduino Nano will convert the data into the form of audio as the output result. The speaker will release the audio according to the money or colour which detected, the audio output will be identified by the blind people.
