How would I go about putting in an LED for my battery so that I would know when to charge it?
I don't need anything fancy. I was thinking just an LED that turned on when my voltage dropped, but I have no idea how to do this.
Damn, it would probably help if mentioned I am using a 7.4 Li ion battery. I have found posts online on how to make a similar indicator, but it had two LED's and I only want to have an indicator with one for when the volatage drops, having a second is just too much extra work for someone lazy like me, and IMO irrelavant. If I new how to properly wire a trimmer pot, resistors, transistors and the LED I wouldn't bother asking, but unfortunately I don't know enough about circuitry yet.
Hey, making some projects from my book? Got a question about something? Wanna share what you've done? Here's the place - go for it!
