Coin Acceptor Based Vending Machine using Microcontroller ijtsrd
This paper investigates based on coin acceptor vending machine using microcontroller system. Technology has become a part of the different aspects of peoples’ lives as it makes most of their work faster and easier. One of the fast paced technologies is the vending machine. It is a machine that dispenses automatically, products such as beverages, tickets, snacks, etc., by inserting currency or credit to the machine. Vending machines appear in different forms and functions. These are generally used in public and private areas such as malls, markets, business and government offices, schools and along the streets. This paper proposes the design of Arduino based automatic vending machine. The main objective of this paper is to launch new technology application in society. In this proposed system, Arduino Mega board, Liquid Crystal Display LCD , coil acceptor, servo motor, stepper motor and push button are used. The rectifier circuit is used for power supply and step down DC to DC module is used to reduce the rectifier output voltage 12V to 5V. Mega is mainly used to run the program for the vending machine. LCD is used for showing the information, for inserting coil and making a selection. The user can choose the product by touching the related button. Four push button are used to choose four different types of product. For the servo motor, it is used for the dropping of the product.
