Automatic night light
Here is an small circuit consisting of very few components to build a automatic self sensing night light. The light bulb used here would go on as the day light fades. As some times in night time also we need to switch of the light so I included even the switch S1 so that we can turn off the light in the night also if not necessary.

Parts list:
R1 : 10M ohm 1/2w
LDR (light dependent resistor)
SCR : 2N2601
Triac : 2N5757
Lamp : 60w bulb
S-1 : on/off switch
s-2 :DPDT switch
FUSE :3A rating
