Development of Material on Auto-tuning Measurement System using Arduino with DAC and MATLAB

Abstract

Recently the higher education system such as university and college etc. became to introduce a microcomputer by a class of practice and graduates study easily from the viewpoint of cost and convenience by the spread of relatively low-priced microcomputers in a product for beginners such as Arduino or Raspberry PI easily. However it is not possible to develop the measurement system teaching materials that a control object needs an analog signal because most microcomputers are not equipped with a DAC function basically. Therefore we develop the teaching materials of the measurement system that tune the offset of the amplification circuit automatically by Arduino using DAC and MATLAB as one example in this study.
