9V Low Battery Indicator Circuit

9V Low Battery Indicator Circuit

Hi,

I just had a question about how I could use a 12V instead of 9V.

Also, what are the values that I should change to let the green LED on from 11.5V and above and the red LED on below 11.5V?

I think it's the resistor values in front of the base but not sure about the calculations.

 

Thanks,

Connor
