An Arduino-based Portable Oscilloscope

Oscilloscopes play a crucial role in electronics and electrical engineering by enabling the visualization and analysis of electrical signals. However, traditional bench-top oscilloscopes, while powerful, are often bulky and expensive, limiting their accessibility and portability. This paper addresses these challenges by proposing a portable mini oscilloscope based on the Arduino NANO microcontroller, offering a more accessible and affordable alternative. Additionally, the software components responsible for signal processing, data analysis, and display rendering are discussed to highlight the oscilloscope's versatility and effectiveness in real-time signal analysis. Performance evaluations of the portable mini oscilloscope demonstrate its capabilities and limitations, emphasizing its potential applications in educational, and professional settings. The Arduino NANO microcontroller provides a versatile platform for signal analysis, making the oscilloscope suitable for a wide range of users. Overall, this paper showcases the portable mini oscilloscope usability, effectiveness, and potential for further improvement, positioning it as a valuable tool in the field of electronics and electrical engineering.
