Hello everyone-
I have an arduino that is going to be used near a window, and I wanted to find a way to hook up a solar cell to a 9V battery, so that during the day, the arduino has power, and at night it just rests without discharging. Is this something that would be easy to do? I have a 170mAh NiMH 9V, and a 9V, 1.5W, 167mA solar panel from radio shack (item number 2770053). Is there any tricky wiring to get this to work? And how do I prevent the battery from discharging into the solar cell during the night? Any help would be greatly appreciated. Thanks!
