Realize GBF using Microcontroller PIC 16F877A

Abstract

For several years, the wave generator has been in great demand among users, both in industry and in research facilities, the considered current source makes it possible to provide a good signal in all possible varieties that we need in various experiments. Pulse waves are usually used by changing the amplitude and pulse width. In this project, we applied an electronic circuit that makes it possible to produce pulsed waveforms whose amplitude and pulse width are modulated using a microcontroller. This circuit envisages applications in the field of scientific research, in particular in the improvement of thin films for solar cells and gas sensors.
