Measurement of deformation presents great importance at development, supervising and optimization of product as they would be optimal characteristic. In theoretical part of work is clarified what is Arduino platform and why is exactly she selected for making of developed system for measurement of deformation. In continuation of theoretical part is explained dependences between stress, strain and electrical resistance whose dependences represents the foundation for understanding deformation measurements. Wheatstone bridge is also clarified which has great significance due to its sensitivity and serves to have its measured voltage values be the first values to be subsequently converted to give the values in desired shape. Likewise, its sensitivity poses a challenge in setting the zero state in which objects is unloaded. The way in which the desired values are obtained by measurement is achieved by calibrating the system with known masses and selecting the appropriate calibration factor, the method of obtaining is explained in detail in the paper. Possible ways to reduce the possibility of errors may be due to temperature changes or ways of connecting electronic components is explained on theoretical level with various ways of connecting the Whetstone bridge and using multiple of electrical conductors per strain gauge to further reduce errors. The components required to make measuring amplifier are also described. The experimental part shows the measurements in the full bridge that has already been performed on load cell as well as the connection in the quarter bridge and half bridge and the conclusions that are obtained. As a final measurement, a half bridge measurement is shown on a four-point bending device. The last chapter before the conclusion presents a comparison of conventional system with the developed system where the methods and components of conventional system used to be able achieve high accuracy measurements are described.
