I have designed the attached baterry indicator circuit for a 12 volt battry but for some reason in multisim it just won't work, was working before I put in the 100 and 200 R resistors in series and was just using a pot in their place.
The idea is that this will be used with a tri-colour led, so read is to come on under 12.5 volts and green is to come on over 11.5. so with a tricolour led between 11.5 and 12.5 both lights are on and it goes yellow/orange.
Any suggestions of what I'm missing ?
does anyone know of some good resources for design using comparators ? I can remember what the configurations can do but now how they are wired up.
