Hello all! This is my first post.
Let me start by saying I am very very new at circuits so go easy on me haha.
I am using this circuit http://imgur.com/eUil72x
it works perfectly. Basically it fades an led from green to yellow to red as the battery runs out.
However, now I want it to work while charging the battery. So as the battery charges the led goes from red to yellow to green as the battery goes from dead to full charge.
But I have no idea how to get the circuit to read the voltage from the battery and not the power adapter that I am using to charge the battery!
Please help!
