DIY Simple LDR-based Day Night Switch, LDR Dark Activated Circuit relay
A simple LDR(Light Dependent Resistor) based ciruit to Turn ON a connected relay. Cicuit is available on many free sites on internet, it consists of only one Transistor, one resistor, one relay, a potentiometer and a Light Dependent Resistor. The circuit would need a little more light than where it switched ON, this can be adjusted using the connect potentiometer, you can see near the end of video i had to show a LED torch to LDR to turn it OFF.
