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

Abstract

now days the Plastic is one of the most versatile material. These days the waste generated by humans. In this paper we develop the VM and RVM . A VM is an automated machine that provides three different types of items such as coca cola, sprite and thumbs-up etc. the money is inserted to consumers in to 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
