Study and Design of Microcontroller-Based Automated Voltage Pulses Tester

Abstract

A voltage pulse test is essential for assessing the integrity of electronic components. Traditional methods tend to produce inaccuracies and labor-intensive results. In this paper, we present a low-cost, automated voltage pulse tester that can improve the accuracy and efficiency of its measurements. The system is composed of an Arduino microcontroller, a high-precision voltage sensor, and a user-interface that can be used to visualize and control the data. The automated tester was evaluated in several tests to confirm its performance. Different parameters, such as duration, amplitude, and repeatability, were analyzed to compare its measurements with those from an ordinary oscilloscope. The results indicated that the automated tester was able to provide high accuracy, with only deviations of less than 1%. Consistent repeatability tests were conducted on the automated tester, which indicated its reliability. Its response time of 50 milliseconds provided a satisfactory assurance that it can handle real-world applications. The results of the tests indicated that the automated tester, which is mainly composed of a microcontroller, is a reliable and robust tool for measuring voltage pulse signals. It offers significant advantages over traditional methods, such as ease of use and accuracy.
