Educational: first step to learn designing electrical system. microcontroller programing

this is a educational video and in this video we are trying to start designing electrical system in practical way. we start programing microcontrollers and step by step we going to use other components. in this method you can learn and with each video you can design a whole new system.
you can find all the files from this link:

so if you are planning to learn about this stuff.. stay tuned....
good luck.
this videos are suited for kids, students and anyone interested in designing robots, automation system and etc.
in this video we are talking about:
