  8. Good Post, easy to understand.

    If you want more knowledge on Electrical Circuit Diagram or any projects on Microcontroller in the field of electronics, you can surf the EG website. For engineering students from various departments, require more information about final year projects. The last year project is challenging work for every engineering student. They need to do many researches, and analysis about their projects with creative ideas. Nowadays , many project are available on Google Search Engine. Engineers Garage is the website which is only for Electronics and Electrical Engineers. Where students can find various Projects ideas and tutorials on Micro-controller, Electric Circuits and more.They develop, train and guide the students to make best score in final year project. In this case the students gain more knowledge about engineering projects. You will get the idea of different micro-controllers like Arduino, ARM, PIC, Raspberry, 8051. You will also find IOT projects which is going trending these days.
