hello
need help here
am new at electronic sensors
anyways heres the problem
a 12v solar panel will charge a 3.6v battery (which powers a LED lamp)
it will charge it during the day (obviously) and the lamp will be used during the night
theres a twist here...the batteries will be charged Automatically from the solar panel and turn OFF the LED lamp during the day; and eventualy disconnect the batteries from the solar panel and turn on the LED lamp at night...
i can visualize the problem and it seems like it requires a photosensor (i was thinking of a photocell, but its quite large though) i am not sure how to construct the control circuit itself
