hi ,,please ineed help,,,I have aproject that make a voltmeter can measure voltages from 0-15 in digetal ,, but its should be in ranges by using at first switches connected with conditioning circuit,, the ranges from 0-5 ,0-10 and 0-15
but we must have 4 push buttons these :3 are used to read the voltage after the corresponding range selection switch is closed, and 4th used for power save
last thing we have The voltmeter is equipped with a buzzer that is activated as long as the input voltage is outside the selected voltage range.

;;;;and thank you
