- Now a day’s water vending machines are available and operated only on coin but our aim is to design water vending machine which is operated on RFID thus it's straightforward for any manifest user to access the vending machine without cash. The designed system basically has RFID as input and purified water through solenoid valve as output. What makes this project unique is it is solar operated which will be more helpful in rural area as there is problem of electricity. The main part is control system which includes C programming in Arduino ATMEGA 328 microcontroller to control various components in system. The major advantage here is there is no need for any mandatory person to take care about the system. This project makes things easier, simple and time efficient at low power consumption.
