Application of Arduino Platform for Measuring Mechanical Vibrations

Abstract

This paper presents the usage of open source hardware and software for measuring mechanical vibrations. The process of constructing the vibration measurement system including the Arduino UNO R3 ATmega328P microcontroller and Analog Devices ADXL335 accelerometer is described. The program for data acquisition is written in C++. The program for signal processing is written in Python. Vibrations are measured on the steel beam with overhangs. The obtained results are compared with the results measured with the MGCplus data acquisition system and Silicon Design 2240-002 accelerometer.
