Rancang Bangun Sistem Pengontrol Suhu pada Coffee Maker Menggunakan Sensor DS18B20 Berbasis ATMEGA328P dengan Interface Android

Abstract

An automatic coffee brewer has been made by utilizing the Arduino microcontroller as the command and control center of this automatic coffee brewing program. Other components that complement the automatic control devices are RFID, Servo Motors, DC Motors, L298N Drivers, and DC Water Pumps. Thehus button is used to enter inputs to select coffee flavors which will be processed from three flavor variants contained in the tool, RFID (Radio Frequency Identification) is used as the initial input of a command that aims to read the code from the card, if the code is correct then the DC motor will move by bringing an empty glass to a container containing sugar and coffee, after the glass is right below the container storage of coffee and sugar the servo motor will live to move the valve that closes from the container, the glass containing coffee and sugar will then move again to the pumping place to dissolve the coffee, after the glass is full the pump will die and the glass will move again to the original place and the coffee is ready to be enjoyed.
