Desenvolvimento de um sistema de aquisição de dados utilizando uma placa Arduino UNO ATMEGA328P para aplicação em potenciostatos

Abstract

This document describes the development of an End-of-Course Project regarding an electronic data acquisition system for application in potentiostats, equipment responsible for controlling electrochemical reactions over electrodes. The acquisition was carried out using an ATmega328P microprocesser, a board containing a microcontroller whose popularity has grown in recent years for the reason that it is cheap and simple to program. It became necessary to develop a printed circuit board that would unite the electrochemical controller circuit and the described embedded system. Once the measurement instrument was properly calibrated, it became possible to analyze the test results that require the use of potentiostats to ensure the proper functioning of the device, which in turn showed consistency when compared with a reference equipment.
