Hello
i want to built a circuit that will give me "1" when the voltage is higher then 10.5V and "0" when lower
this circuit need to be connected to a battery and a digital I\O - so when it does under 10.5V I will know I need to cahnge the battery soon.
so I only need it to be as small as possible and will use very low current
I was thinking of using LM741 (will work on 12-10V ?)and connect to him a D flipflop maybe ?
this is a sketch of what I have in mind
but how do I make it compare from 10.5V -
all use the same battery
Thanks ,
