“Making an Aquarium more attractive.”

The LED illumination circuit is designed to light a 4×12 ft. aquarium using LEDs. It uses uses 74LV4060D IC, a low-voltage Si-gate CMOS device that has a 14-stage ripple-carry counter/divider and oscillator optimized for low voltage applications. The IC is responsible for the lighting sequence of the circuit where the blue and white LEDs light alternately at an interval of 12 hours.  Read more
