A modern gauge has been fused with digital and processor means of managing and processing information. Digital-to-analog (DACs) and analog-to-digital converters (ADCs) are widely used in various fields of modern science and technology. It is proposed to use the computer on the physics lessons and related subjects as the universal electric measuring device, which is based on using ADC and DAC audio adapter with an emphasis on the use of elements, means and principles of programming in its software. The study considers two aspects: methodology of teaching physics, gaining the professional competencies by engineer-programmers.
