Integrating Maker Education into the Research Project of Undergraduate Chemistry Program: Low-Cost Arduino-Based 3D Printed Autotitrator

This project was designed to incorporate maker education into the final-year research project of the undergraduate chemistry program. It involves taking a project from concept to prototype through project-based learning, emphasizing hands-on learning experiences to solve real-world problems. A final-year undergraduate chemistry student was involved in this work. This student identified a problem through a literature review, designed the necessary equipment, built the prototype to address the identified problem, and assessed its performance using statistical methods. The student successfully developed a low-cost autotitrator using Arduino Uno-compatible microcontrollers, a pH sensor, an open-source PLX-DAQ data acquisition system, 3D printing technology, and various electronic components for determining the percentage of total acidity in fruit juices. Engaging in this project significantly enhanced the student’s technical skills and developed problem-solving abilities, critical thinking, and creativity, which are essential for the future workforce. Additionally, this project enables chemistry students to gain a deeper understanding of the hardware and equipment development process. Moreover, it trains students in utilizing open-source software and identifying cost-effective solutions for building prototypes to solve real-world problems. The concept of this project is adaptable and can be applied to train students in designing and building various chemistry-related equipment.
