PENGEMBANGAN TIMBANGAN BUAH ANALOG MENJADI DIGITAL BERBASIS MIKROKONTROLER ATMEGA16 DAN TERINTEGRASI ANDROID
Abstract
A scale is used for measuring the load. The digital scale is developed to help the user in reading the measurement and to avoid a mistaken measurement.
In this research, the measurement of load used a sensor, which is known as Load Cell. As the result, the output voltage is then converted into digital data by ADS7822. The resulted digital data is further processed by microcontroller ATmega16, hence the data can be visibly displayed in the LCD screen along with its gram unit. The data can be accessed by android apps named Fruit Scale. This app is programed using App Inventor and it is connected using Bluetooth HC-05.
Based on the measurement of determined loads using the developed digital scale, showed that the results was consistent with the weight of determined samples. The apps and the scale are well synchronized, so the apps can be installed in any other devices.
