RANCANG BANGUN SISTEM OTOMATISASI PADA CUSTOM ICE CRYSTAL MACHINE
Ice crystal is a daily needs for consumables, so that it needs an inovation that serves as a support to sover the needs of ice crystal. For the performance of tools needed automation made to facilitate the performance of this ice crystal machine, with the main drive of the DC motor made for the ups and downs of the plate as a mold for this ice crystal, then in the automation writer uses Arduino as a micro-controller that will capture the DS18B20 sensor. with a DS18B20 sensor that can capture sensors below -55 ℃ so that when the ice crystal is frozen the sensor will read and move the DC stepper motor that makes the automatic plate down and the ice crystal attached to the evaporator will be released with a reverse process on the system. Ice crystal will fall automatically and prepare a tray as a base to hold the ice.
