thanks everbody for your answers...Sorry, i didn't remembered it is a comparator (i suppose i have to use a 741..do i?)...and answering your question, yes, it's a class project but we have to decide what to do, so i thought it was a good project 'cause we were learning how a basic voltmeter works and how the adc's makes the conversion and i think it would be cool to make both work together but i don't know if it's possible to read the voltaje (with the voltmeter) and display it in 7-segments displays with the ADC...if anybody can help me answering i'll really appreciate it...
