Android Multimeter

Abstract

The main objective of this project is measure the voltage of electronic circuits (max range ± 15V). Firstly an Arduino will be programed to control and measure automatically electronic circuits. This tool was introduced in 2005, the Arduino platform was designed to provide an inexpensive and easy way for projects, students and professionals to create devices that interact with their environment using sensors and actuators. It comes with a simple integrated development environment (IDE) that runs on regular personal computers and allows users to write programs for Arduino using C or C++. Secondly the value will be sent to a platform which its operative system is Android. This OS based on the Linux kernel with a user interface based on direct manipulation, designed primarily for touchscreen mobile devices such as smartphones and tablet computers. The operating system uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard. Despite being primarily designed for touchscreen input, it also has been used in televisions, games consoles, digital cameras, and other electronics. Finally all of this knowledge will be applied in a PCB which will be built by Op. Amp, multiplexer, resistors and Zener-diode.
