Study of Solar Powered Vending Machine

Abstract

Over the past few years, there has been an emergence of vending machines that provide a wide range of products, including drinks, chocolates, and even medical supplies. However, access to first aid kits remains scarce in many public areas such as schools and transportation hubs. This paper proposes a solution in the form of a solar-powered, RFID-based vending machine aimed at dispensing essential first aid supplies and stationery items. The system combines an Arduino Uno microcontroller with an RFID reader to ensure secure and automated dispensing of items. By using renewable energy, this machine not only increases accessibility and efficiency but also reduces reliance on traditional power sources. Recent advancements highlight the growing trend toward automatic and solar-powered vending systems, reducing the need for manual operations while boosting energy efficiency (Kumar et al., 2020).
