Actually I love Electronic as much as other branches of physics. as I can remember I spent all of my time to learn electrical sciences and earn any experiences that could be have an electronic achievement. I started from Analog and Simple TTL circuit and then starting to programming on 8051 Micro Controllers when i was 14 years old. then i used to make my projects with AVR , PIC and Xmega Micro controllers.in that while i had enough time to make an experience in other parts of electronics like Precision Analog circuits, some types of sensors and many electronic modules to done what i want.and eventually about 8 years ago i started to learn more expert processors and electrical projects. for about 8 years i'm working on ARM and professional C++ Firm work that i created it and i could earn a lot of designing skills around Instrumental, Telecommunications, user interface and graphical , electro-mechanical , positioning and sensing, industrial Control and back end programming systems.
