Prototype Design of MCU-Based Coin Operated Printer

Printed document, such as term papers, researches and the like are one of the requirements a student must fulfill, however, inaccessibility of printer inside the campus has been an obvious dilemma in MSEUF, Lucena that must be dealt accordingly. The goal of this study is to provide the student, mainly the engineering students an accessible coin-operated printer inside the department. Research and development was implemented in this study to accurately find the ways of developing already existing design of previous studies resulting to an upgraded quality of operation through the application of different technological advancement. The study consists of coin acceptor, Atmega328, microPC, servo motor, printer, and monitor powered by a supply voltage of a regulated 5V and 12V DC. The use of Sonar sensor gave a process start indication to the system. This additional feature makes the whole system operates as desired. The testing and evaluation of MCU Based Coin Operated Printer has turned out successful and fulfilling as with the objectives. Most of the respondents find it convenient and accessible; they agreed that the functionality, reliability, and effectiveness will be suited for students and others as well.
