Hi.
I have a circuit with 3 voltage levels: +40V, +8V and +5V. I want to detect if these voltage levels are present using 3 LED's.
My idea is that when the voltage levels are below 10% of the required levels, so +36V, +7.2V and +4.5V respectively, I want the LED's to turn on. When the voltage levels are above, they turn off.
Any idea how to do this, maybe using comparators?
