Design an Arduino-based rice ATM machine system using RFID and ultrasonic sensors

Abstract

A system design for an Arduino-based rice ATM machine using RFID and ultrasonik sensors with a quantitative research method has been created which aims to produce an automatic machine for distributing rice to the public. This machine uses the Arduino Uno microcontroller as a controller. The supporting sensors used are Ultrasonik Sensors as a detector for the amount of rice and RFID (Radio Frequency Identification) as an Activation card reader used to take rice ina rice ATM machine while the output used to run a rice ATM machine is a Servo Motor, 2X16 LCD, and Buzzer. The results of this study have satisfactory results because each component tested and used in rice ATM machines is able to run the controller program ordered by Arduino to issue rice according to the expected amount and detect cards that do not have access, also detect rice balances and are very easy to apply. In public, this can be proven by testing carried out both for each component or machine testing where RFID is able to read the   frequency from the RFID card and ultrasonik sensors can detect the amount of rice and provide a code using a buzzer and LCD is able to display every information from every situation in a rice ATM which the user can read and understand as well as the mechanical system of the servo motor which is capable of moving the exitdoor for rice containing more than 15 kg.
