Automatic Solar Light Circuit

Automatic Lights ON Garden Solar Light Circuit

This circuit will switch on a LED automatically when it detects darkness.

Detecting Darkness
The battery is continuously charged via the solar panel during the day. The solar panel serves as both the battery charger and the "darkness" sensor. The 2n3906 PNP transistor base switches on (become negative) when it is dark and switches on the LED.
