Abstract

The Mixing Process of milk coffee use two sensor that is water level sensor to know boundary height of water and thermostat or temperature switch as temperature control if the water temperature at basin mixer have reached temperature which have been determined. basin mixer number 1 attached by temperature switch with maximum temperature range 82 celcius and basin mixer number 2 attached by temperature switch with temperature 70 celcius to maintain water remain to heat. The System from this appliance is started with the mixing process of three materials type that is coffee powder, sugar and milk using stepper motor which have long time setting opening by mikrokontroler . At the same time with process, temperature and heat switch activated to limit temperature and heat water furthermore the pump at basin materials will be active to fill basin mixer number 1. Pump will stop to fill the basin mixer number 1 if water have reached the range of upper level so that the sensor water level will get input of logic high or 1. After sensor of level water deliver high logic to mikrokontroler hence mikrokontroler will activate mixer to swirl third mixture [of] the materials during which is determined. When the water temperature have reached temperature 82 celcius hence mikrokontroler will give low logic or 0 to and mixer of heater so that the two in a state of is inactive.
