A Study on the Development of Battery fuel gauge using Arduino

Smartphone, that is one of the biggest changes of recent information technology, simply to provide a variety of information and services. Although we can communicate at high speed using the 4G system, it is essential to have extra portable batteries for people who are using the smartphone because of severe battery consumption. However, the remaining capacity of a battery is not able to know from just looking at. Therefore, in this paper, we will develop a battery fuel gauge by using the current sensor and arduino. By measuring the voltage of the battery, it indicates the degree of charge by displaying color change of LED depending on voltage.
