Automatic Cold Drink Vending Machine with Reverse Vending System for Empty Bottles and Monitoring System

Abstract
Plastic is one of the most versatile materials of our modern age and yet the popularity of plastic is the problem. These days the increase in amount of waste generated by humans and limited landfill sites for dumping waste, recycling is one of the novel approaches to manage the waste effectively. In this project we implement the vending and reverse vending machine. A vending machine is an automated machine that provides three different types of items such as coca cola, sprite and thumbs-up etc. to consumers after money is inserted into the machine. The reverse vending machine is the machine that accepts empty plastic bottles and credits discount offer. The collected empty plastic bottles are sent for further recycling which is environment friendly. Operation of the machine exhibited accuracy in recognizing barcode data, distinguishing between vend plastic bottle and other plastic bottles, storage update. The machine is able to run on commercial power. All the mentioned process will be controlled by a PIC microcontroller. Throughout the process barcode sensor is responsible to Identify vend plastic bottles. The developed project is environment friendly and cost effective.
