A potentiostat is an instrument that aids in electrochemical studies. It is employed in various studies like amperometric, potentiometric, and electrochemical impedance spectroscopy. Potentiostat controls an electrochemical cell where the applied potential or current is varied, and chemical reactions related to variations are studied. The findings from the potentiostat help in quantitative and qualitative analysis of the sample of interest. Usually, a conventional potentiostat is priced high and requires a laboratory setup for its working. To make a potentiostat at a low-cost and portable, microcontroller along with operational amplifiers and other electronic components can be used. ARM architecture-based 32-bit microcontroller-STM32 Nucleo-144 board applied in the construction of microcontroller potentiostat. DAC and ADC functions along with the functions of operational amplifiers are implemented in the design and working of the potentiostat. A 32-bit microcontroller is employed due to its high operating speed and wide resolution. The designed potentiostat can be interfaced with an LCD or serial plotter to gather the required data for the analysis. The advantages of microcontroller-based potentiostat are factors relating to cost, portability, and ease of usage.
