Nowadays the priority is to take measurements with a computer or automatic measuring system so you can store the measuring data, compare them with other data or perform various comparative, logical and arithmetic operations. This allows us to speed up problem solving significantly. However, sometimes we are forced to use older equipment that is not automated and it does not allow to communicate with computer to store data.
In the task I have described one of the possible ways of automation manual potentiometer. In the particular case – measuring hysteresis curve I have tested what is the functionality of the system I imagined.
Automation system is efficient if the system is faster and more precise than the manual measurement. I tried to find the simplest solution with relatively simple equipment both hardware as well as software.
I tried to solve the problem with a stepper motor attached to a carrier disposed adjacent to the device which we want to control.
