I need help buying a simple circuit. What I need to do is simple, I need to power 16 white LED's and 8 blue LED's. I tried building a circuit from somebody else and well, it didn't work. LED Aquarium Lighting This what I was aiming for, except splitting the amount of lights in half. I could of just messed up the circuit board when I was building it. (It was my first one). Could somebody help me build this circuit. Never done this before. Thanks.
