The design and constructions of a portable, battery powered, completely Arduino controlled Cyclic Voltammetry instrument (CV) is presented. An Arduino Uno, a soldered prototyping shield, and a LCD/SD card shield for real-time analysis display and data logging were installed in a project box. Arduino’s (Integrated Development Environment (IDE) and their many application examples were used to write the control software. Analytical chemistry students often study basic electronics and breadboard instruments in order to better understand their design, functions, and analytical errors. An undergraduate research student conducted lab and field-testing of this instrument. CV experiments with dilute concentrations of Lead, Cadmium, and Copper ions are presented to illustrate the effectiveness of the design and the learning experience. A high correlation of oxidation and reduction peak heights with concentration is shown over a wide range of concentration. There is good agreement between this portable Arduino instrument and a commercial CV instrument.
