We are creating an automated aquaponic system with mobile updates via Twitter. Sensors and motors will be controlled from an Arduino while the entire system, including mobile updates, will be orchestrated by a Raspberry Pi. Tweets include pictures, sensor data, and system-critical updates. Original system schematics have changed a little but not much. We only used (2) relays and the LCD was attached to the Arduino, and the pH sensor didn't make it into the system as of our due date.
