Sounds like a good job for a simple microcontroller. I dont have much experience with microcontrollers yet. (Still working on that degree
) Sounds like a neat LED
lighting display for an aquarium.
Depending on how complex you want to make things, you could get by with a microcontroller turning on and off LEDs via some transistors. The hard part would be writing the code. (well if you have no experience with that).
Any other EE folks here? You may want to take this to another forum. I am a member over at 4hv.org. Lots of EEs and computer programmers over there. Youll likely get free advice if you give a bit more details, or you can easily find several eager EEs willing to do it for a price.
