circuit design part 1

 i start my second part of my final year project by designing circuit schematic. i used EAGLE ( Easy Applicable Graphics Layout Editors as a schematic designer. this software is developed by http://www.cadsoftusa.com. The component libraries supplied with EAGLE have been compiled with great care as an additional service to me. However, the large number of available components and suppliers of these components means that the occasional discrepancy is unavoidable.  

 after the designing is completed. i have to convert it to the PCB layout. this step will show the link or connection between component before do the etching process
