Hi All
I am trying to make a simple battery monitor showing bad fair food and over charging using zener diodes and resistors. I know how to work out the value of the Resistor but how do I work out the value of the Zener diode, if I want the LED for arguments sake to illuminate at 12 Volts, do I put a 12 Volt zener in this is the calculation I amtrying to find.
Many thanks
Rodney
