Dark
Activated Switch or Porch Light Switch This circuit will activate a relay
when light falls to a preset level. Light level can be adjusted with VR1 and the
relay contacts may be used to operate an external light or buzzer |

| Dark activated relay There's two schematics, one for light activated relay and
one for dark activated relay. When the light / dark hits the sensor a relay will
be activated |
