Improvement Development of Bill Acceptor for Laundry Application with Internet-of-Thing as Notification

Abstract

Nowadays, self-laundry kiosk service has been widely available in Malaysia. Although the technology has been progressing rapidly especially the technology of Internet-of-Thing, most of the system used by the self-laundry machines are outdated. One difficulty faced by the owners of the self-laundry kiosk, they need to check frequently by themselves at their cashbox machines in order to check whether the cashbox filled or emptied. This leads to inefficiency and can be addressed if self-laundry machine is integrated with Internet-of-Thing technology. Thus, this project attempts to improvise the current system by developing the bill acceptor that gives the owner to monitoring the flow of current amount inserted by customer in real time by displaying it in apps at owner smartphone. The project uses Arduino Mega as a controller, bill acceptor machine as token receiver, Wi-fi module to send the data to apps, LCD and Blynk apps to display the current amount and Bluetooth module to communicate between the Arduino and the washing machine. A checklist analysis and scenario analysis are implemented to verify the functionality of the proposed prototype. The result shows that the proposed prototype achieve all the objectives required.
