Vending Machine: A Vending Machine

Abstract—Since their introduction, Vending machines have become an increasingly important distribution channel in public and private sectors. A Vending machine is an automatic machine that sells food such as canned soups and packaged sandwiches, snacks such as potato chips, chocolate bars, and candy); hot drinks (coffee, tea, and hot chocolate); cold drinks (juice, bottled water, soft drinks, and in some cases, milk or chocolate milk); or other items such as newspapers. Same in proposed system, we are using Arduino controller for making vending machine. Here we are also using RFID tags for authentication so that wastage of water and beverages will be controlled. In this system we are using three sprinkler motor, three switches to choose an

used to sense ID. Another part consists of programming which is implemented through microcontroller. The display unit display information, according to that information, microcontroller gives input signal to the drink output unit. In this project we have tried to design a low cost, accurate and portable vending machine. This project is based on the embedded system also called the smart system. An embedded system is a special purpose computer system built a large device. It is the hardware and software that form a component of large system. An expected to function without human intervention an embedded system is required to meet different requirement than a general purpose personal computer. Embedded system often used a slow processor and small memory to minimize the

As per the business trend of our Society, Vending machine is totally a new concept. It is not widely used here. So for enhancement of technology in our society and for its further application, the project idea has been designed. Our project can be simply viewed as the machine that vends cold drinks in cup. Here we have facility of vending two different types of liquids. Generally in market it is found that products are vend as per the pet bottle but with regard to the customer desire, this machine helps to dispense as per necessary. It is user friendly and very simple in operation. Its simplicity within the complexity is its main feature. Commercially over viewing, the main objective of our project is to launch new technology’s application in the society. The project has vision that this may be the milestone product of technology in the Market.

III. METHODOLOGY

Project development is not an easy task. It requires thorough study of the various component and their outcomes. The project is effective only if it can fulfill the objective that it aim to provide The project is implemented using various that are organized in a specific way so that the device is small and portable. Each component has a specific function to perform. Our project is basically divided into three parts: mechanical, electronics and display unit. This part consists of various components, which are
