Imagine for aquarium lighting that gives a natural look, which is automatic and still use LED bulbs. That must cost a fortune, but even if you build a schema of LED lighting that turns on automatically at sunset, off at dawn and switches the white, blue and green to give a different touch to the aquarium can get cheapie as in the above schema.

The interrupt schema uses an LDR light sensor as making automatic switching, activating IC1 CD4060 which is a binary counter with 10 outputs, mixing colors and creating a colorful beautiful to the bottom of the aquarium tank.
