Abstract: The study presents cheap vibration measurement approach for dynamic responses of fixed-fixed beam model by using Accelerometer and Arduino Nano board. Low-cost MEMS (MMA845X) with triple axis accelerometer are programmed to connect in Arduino Nano microcontroller board via standard I2C bus. The MEMS signals in real-time are collected by embedded codes in Matlab and Arduino software over the serial communication. MEMS data of historical responses on steel beam from Arduino Nano are analyzed to calculate fundamental frequency via fast fourier transform (FFT) algorithm. The natural frequency of beam is measured, compared and predicted with commercial calibrated accelerometers.
