A photoresist can be used to control a led. the led can be turned on and off based on the amount of light falling on the photoresistor
we can either use a potentiometer to vary or set the amount of light required required to turn the led on or off or we can use resistance using voltage divider rule given by
Vout=(R2*Vin)/R1+R2
here I have used 2 resistance based on the values calculated
below I will be showing the working and simulation part

above is the list of components required

above is the circuit diagram for the same
the connections are made as follows
when the light falls on the photoresistor the led turns off
and when the light turns off the led turns onnnnn

the simulation link is given below

the actual physical working models YouTube link is below
