Inexpensive Miniature Programmable Magnetic Stirrer from Reconfigured Computer Parts

Abstract

This technology report outlines a robust and easy to assemble magnetic stirrer that is programmable. All of the parts are recycled from obsolete computer hardware except the Arduino microcontroller and motor driver, at a total cost of around $40. This multidisciplinary approach introduces microcontrollers to students and grants the opportunity to interface basic computer programming with practical applications in chemistry. Utilizing the popular Arduino board empowers students to control laboratory devices, which in turn enhances enjoyment and understanding.
