I'm trying to build a simple circuit to indicate the status of my 3.7v lithium ion battery.
When the battry goes down to 3.0v, the LED should be turned on. It should be turned off when it is above 3.0v.
Or When the battery goes down to 3.0v, the LED should be turned off. It should be turned on when it is above 3.0v
So 3.0v is what makes LED different from the original state.
I've been trying to build this circuit using BJT but it does not seem to be working.
I'm a bit short of time. Please help. Any tips, links, help will be appreciated.
