Evil Mad Scientists have put together a nice Darkness Sensing LED Circuit that senses darkness using a phototransistor to detect light. “When light falls on the phototransistor, it begins to conduct up to about 1.5 mA, which pulls down the voltage at the lower side of the resistor by 1.5 V, turning off the transistor, which turns off the LED. When it’s dark, the transistor is able to conduct about
