Even after we got the individual components working, we had the issue where the components were not working together as a system. We had the issues with the pumps where if the bucket of water was not aligned correctly, it could cause a vacuum that sucked out all the water even after the pump turned off. Also, it could cause the amount of water to back wash back into the tank causing no difference in the amount of water in the tank. We tried to solve this ineffectively through the use of valves. We eventually just had to shape the tubes just correctly so that we could make sure the right amount of water was moving in the right direction. Information was not being transferred through serial from Processing to Arduino. We had to rewrite all the coding for the pumps using the API information into Processing. Therefore Processing controlled the pumps through Arduino running Firmata. We kept the bend sensor information in Arduino on a separate Arduino and power source. Also, in the interest of time, we eliminated the 2 extra pumps that would have reset the tanks at the end of the day.
