Innovation Technology of Lekor Dough Mixer Based Internet of Thing

The purpose of this tool is to help lekor entrepreneurs save time and make it easier for entrepreneurs to make lekor dough, because this makes kemplang faster by simply connecting an android smartphone to Bluetooth, the dough mixer can be controlled remotely but still have the maximum distance This tool is controlled using an Android smartphone and then connected to the Bluetooth driver on the device. Meanwhile, to control each component using Arduino. The maximum distance between the Bluetooth module on the device and the Android smartphone so that it can be connected is about 30 meters. The one that controls the system in this tool is the Arduino Uno. The program used in this tool is the MIT App Inventor. At the measurement of test point 2 on the Stepdown Vin module of 5.29 Volts, and Vout of 24.04 Volts. The DC to DC LM 2596 Stepdown Module is a module that has IC LM 2596 as its main component. There are several variants of this IC series which can be grouped into two groups, namely an adjustable version whose output voltage can be adjusted, and a fixed voltage output version whose output voltage can be adjusted, and a fixed output voltage version whose output voltage is fixed. At the measurement of test point 3 on the Bluetooth HC module the maximum distance of Blutetooth is 30 m. Bluetooth HC has 2 configuration modes, namely AT mode and Communication mode. AT mode functions to make configuration settings of the HC. Meanwhile, the Communication mode functions to communicate bluetooth with other devices.
