Hi I'm working on a solar project that hopefully be my base for all my projects under the sun.
currently I charge my battery with a solar panel and read the battery voltage.
I would like to put my board into a sleep/ off/ low power mode) for a minute
and check the measurement.
I would like to disconnect my solar panel if the battery voltage is too high.
than repeat/check next minute
other than removing parts from my board therefore making it low power
what does Arduino offer in its tool bag?
can this be done using the watchdog function?
or perhaps a timer ?
any other ideas
thanks in advance
