i have the circuit built for a 3.7v dc monitor and i would like to adjust the values to read between 3.0V and 4.2V.
i can not figure out for the life of me what the resistor values would be for the upper and lower limit. i know it's got to be simple.
here is my original schematic.. its works great.... but only the problem is it works from 0 to 4.2v...
at 4.2v all LEDs glow.. but at 3.10v only 5 of the LEDs goes off.....
