Guys i am trying to build a battery voltage indicator. I googled and built this circuit from this link
http://www.reuk.co.uk/LM741-OpAmp-Voltage-Indicator.htm
My circuit is not working as it should. I am just lost. Will anybody pl. suggest some other circuit or modify the same so that it works.
My goal is to indicate fully charges at 6V and above, max is 8.4V(Green Led). and 4.5V and below is low battery (Red Led).
