Hi,
I would like to measure the battery capacity (how much longer can I keep the
operating robot, running under the present battery), but I very newbie in
regards to electonics... so here are my newbie questions... :)
1) Is voltage; information enough, to provide battery capacity (left) ?
2) Could I use one of the analog ports on the Handy Board to measure battery
voltage (and therefore calculate capacity left (assuming voltage is
information enough for the calculation)) ?
3) Is there a better way to measure battery capacity?
4) What would be the way requiring "less hardware as possible" (but making use
of the HB), to calculate battery capacity ?
Thank you in advance,
Andre Philippi.

| (...) This is usually how it's done. The voltage will drop predictably as the battery discharges. (...) Yes. You could use a voltage divider. You may have to play with the cutoff point a bit, and be aware that nicads experience a rather sharp (...) (25 years ago, 3-May-99, to lugnet.robotics.handyboard)
