Programming of single-chip microcomputers in a high- and low-level programming language and the basics of robotics, types of signals, their processing and control.
Course Objectives

Acquisition of skills in registration and data processing by computer, measurement of electrical and magnetic quantities. Physical interpretation and written / graphic presentation of processed results.

Syllabus

In the initial two or three exercises, joint acquisition of skills and measurement with analog and digital devices (oscilloscope, digital multimeter, A / D converter), processing of measured data by computer. This is followed by five to six separate laboratory works on electricity and magnetism selected from the offer: electrical properties of substances – electric bridges, Hall effect; electric field mapping; magnetic field mapping – air coils; electromagnetic induction – transformer; electrical RLC oscillations – transient RLC phenomenon, serial and parallel RLC circuit; magnetic properties of substances – hysteresis loops, permeability of substances, separation of magnetic losses; fuel cell; determination of the specific charge of an electron (e / m0).
