This circuit can control the on/off cycle of a light via a CDS photocell, and turn it off after a pre-set period. The light can only be turned on when CDS cell is in darkness, and it stays on for a time determined by the 555 circuit. On time depends on RI and C1 and is about 80 seconds with the values shown.
