Abstract

This project aims to improve the accessibility of equipment used in analytical chemistry practices at IQ USP by developing appropriate tools for undergraduate teaching using accessible manufacturing techniques, such as 3D printing and low-cost microcontrollers. The focus is on developing an autonomous biamperometry device that operates without the need for a multimeter and can record the current values measured by students. Additionally, a more affordable alternative to platinum electrodes will be explored to further reduce costs. The project also proposes the creation of a simple colorimeter capable of tracking the progress of volumetric titrations using visual indicators. This device will convert color intensity information into another sensory format, making it easier for individuals with color blindness or visual impairments to identify the equivalence point.
