Description

The LDR is a light sensitive resistor. In darkness the resistance will increase, thereby increasing the voltage on pin 3 of the Op-Amp; this in turn drives voltage to the output, switching the led on.

Adjust the variable resistor to make the circuit work: in the dark turn the potentiometer until the LED switches on.

Level of this kit is intermediate.
