I have made an automatic night lamp using a 555 timer ic and LDR. the circuit diagram is shown below. the components values are- R1= 1k ohm                                         C1=104 pf R2=100k ohm(pot)                               C2=60 microfarad R3=100k ohm the output of timer ic is connected to a bulb through a relay. As there is darkness over the LDR, the relay is switched on and the bulb glows. but when there is light/day the bulb is off.
