I have been working a bit on my reef controller and I have gotten far enough to show it off. So far everything works just fine except the RTC, it will spit bad data back from time to time. I ordered a replacement chip just in case. Othere than that, here we go:
Here is the boards and wiring. Still need a pretty box to put it all in.
This is the power control unit. It uses 8 SSRs on an American DJ unit.
Here is a mandatory tank shot:
Right now the Arduino controls:
Temp (heater, fan, kills lights if too hot)
Water level (uses float switch)
Power heads (kills pumps for 5 min for feeding)
**Light timer (once the RTC errors are resolved.)
Next component on order is a keypad.
