Greetings all.
I made this simple circuit to turn on 3 led's at night using a comparator. The idea is the solar cell charges the batteries during the day then at night they run off the batteries. An photo resistor does the detecting.
The circuit works ok, however i'v noticed that when daylight comes back in the morning, the circuit isn't snapping off like it should. It works fine when i put some heat shrink over the sensor, then remove it.
Anyone have any ideas why it's not turning off with daylight?
p.s. the solar cell voltage should read as 7.8v.
