Coffee drinks have been long one of the favorite drinks in the world. Coffee roasting process is very influential to the quality and taste of coffee drinks. There are many levels of roasting coffee beans and the difficulty of roasting coffee beans causes coffee drink lovers who don’t understand roasting coffee beans based on the way they want. By looking at above events, then made an automatic coffee roaster machine that could coffee beans roasting for various levels of roasting which can be easily controlled by using a smartphone. Coffee roaster made using Arduino Uno as microcontrollers controlled by Android smartphone applications via Bluetooth. The temperature sensor used in this coffee roaster is thermocouple. The result is a prototype of a toaster that can be monitored and controlled using an Android-based smartphone. From the results of testing tools, was found that the longer roasting time will cause the aroma of coffee beans getting sharper and the color of the coffee beans getting black. The time of first crack of coffee roaster made longer when compared to the branded coffee roasters.
