i need to design a circuit to measure the voltage from a psu in steps of one volt. i need it to range from 4 volts to 15 volts in steps of one volt. i was told to use the lm3914 and a 10 Led display. i cant seem to get this to work. i have it working between 12 to 15 volts but dont know how to adjust the steps to one volt steps. what resistor values do i need and how do i wire this all up?? oh and by the way i have the use the input voltage to power this too...
Thanks in advance!
