Mesin Vending Snack Berbasis Arduino Uno

Abstract

A vending machine is an automated business piece of equipment that provides vending operations at no cost to anyone. They have the advantage of operating with more flexibility in terms of working hours. The control system will enable the machine to handle payments via coins, a high-definition touch-enabled screen. The coin payment system allows the input of a number of types of coins into the automatic open-selling machine to make purchase transactions. The coin payment system allows the input of a number of coins into the vending machine to make a purchase transaction. After the items and quantity are selected, the system calculates the total cost and displays it on the screen. If the coin passes the validation, the system calculates the total coin value and compares it to the price of the selected item. If the value is the same as the price of the goods, then the transaction is complete, and the product is sent through a mechanical delivery system. The way the tool works is that when the device is turned on, the device will initialize it first. After that the coin acceptor will detect the coins that have been entered. If a coin is detected, the snack selection button will open and you are welcome to choose the desired snack. After selecting a snack, the snack will appear. The Arduino Uno-based vending machine tool has been successfully designed and has good performance as evidenced by the results of filling Coins and selecting food running properly. Good. The design of a vending machine using a multi Coin acceptor sensor has been successfully designed, this can be proven by the multi Coin acceptor sensor being able to detect 3 types of coins, namely Rp. 500 yellow, Rp. 500 silver and Rp. 1000, where the multi Coin acceptor sensor will reject coins that are not registered in the Arduino program namely Coin Rp. 100 and Rp. 200. The performance of the Arduino Uno-based Snack machine vending tool is successful, this is evidenced by the work of the tool removing Snacks from the vending machine and where when selecting the Snack token on the LCD it will decrease.
