Micro Controlled Plastic Bottles Collection Machine Based on the Principle of Gambling Slot Machines

Abstract

This paper presents the design and implementation of a fully automated plastic bottles collection machine based on the idea of the luck slot machines. However instead of inserting coins, our machine accepts only empty plastic bottles. Once the inserted item is accepted by the machine, three wheels with fruit logos start to rotate. After the rotation times are over and in case that the three wheels stop at similar fruit logo the user wins.
