System OverviewThe objective of this project is to design and build a fountain control system that will allow the user to create a custom water and light show.

Mechanical System: UIOverride

CommandDescription

PAUSE This commands the system to pause functionality of the entire system. All

streams and colors will remain as they are.

RESUME This commands the system to resume functionality of the entire system. System

will leave the PAUSED state.

STOP This commands the system to stop all operation. Stop water streams and pump, turn off lights, and return to the beginning

of the recipe in a PAUSED state.

PURGE This command will allow the user to purge the reservoir of all its water.

Mechanical System: Pump
