Current battery voltage - how to obtain?

2008-04-03T12:43:00+01:00

I seemed to be having a bad keyboard day the other day re. spelling. From a Servo power pin (middle pin) I have 2 x 4k7 resistors in series to the 0V pin (top pin of A-D port). The mid point of the two resistors I have wired to the A-D input (bottom pin of A-D port). An integer A-D read of the port gives 613 at 6.0V from which I subtract 13 to produce a x10 robot voltage figure.

Any chance to ask you if you could provide some example for this?

Thanks mate.

well I use a 50:50 potential divided from the servo supply to zero volts and read it on the A-D port. Hope that helps.

Is there any chance to retrieve the battery status in Robonova ?

I would like to react if the level falls down below critical

Thanks in advance!
