A modular, customizable, and low-cost experimental control system for electron spectrometers is described. LabVIEW is used to interface with a suite of Arduino-controlled power supplies, detectors, and stepper motors enabling a variety of different types of measurements to be performed. The structure of the LabVIEW control system and the general design of the Arduino-controlled modules are described. Examples of results from electron scattering and electron impact ionization experiments performed using this control system are presented.
