Pembuat Alat Pencampur Kopi dengan Berbagai Opsi Berbasis Mikrokontroler Arduino Uno

Abstract

Serving coffee automatically makes it more practical in making coffee. The benefit of an automatic coffee machine is that you no longer need to add the amount of water and coffee powder needed, which makes your daily activities more effective. Currently there are obstacles to making coffee, namely busyness and busy activities make a person no time to make coffee and coffee machines that are already on the market only have one flavor variant. Based on these problems, it is necessary to make an automatic coffee machine that is not too expensive. The coffee made by this tool has three flavors and a scheduling feature. The results of this research are expected to help in making coffee, which is done automatically. The process of making coffee drinks can run after pressing the menu button options which consist of bitter coffee, sweet coffee, and Coffeemix. This coffee variant mixing machine is designed to meet people's need for coffee drinks with a fast and precise serving process. So this research was carried out to make a coffee mixer with various options based on the Arduino microcontroller. With a Servo Motor to regulate the dosage of coffee, milk, palm sugar and liquid white sugar. The options on this tool are black coffee, sweet coffee, coffeemix. Based on the test results obtained from several coffee mixing trials, it was found that the motor ran well with an average total time of each menu of 5.57 seconds for bitter coffee (Menu 1), 5.53 seconds for sweet coffee (Menu 2) , 5.73 seconds for Coffeemix (Menu 3).
