ADC- Analog to Digital Converter

This afternoon i was hard cording some ADC codes. Actual thing i want to do is micro controller's ADC will analyze the given voltage . Actually i am continuing my voltmeter project. I did analog part from LM358. actually an differential amplifier, it handles the high voltage and gives an out put range from 0 - 5 volt.
After some calculations i finally solve the puzzle. Now my micro controlled voltmeter is able to display variable voltage from GLCD (Graphical LCD). Next step is to fine tune the analog circuit and add a new feature or function to display load current.
Many experiments are hold for few days, thing is me too busy some times... ;)
