Function Description

This is a fully functioning Arduino based hydroponic controller that will do the following:

• Communicate with an iphone application
• The app will also allow me to set times for lights and water pumps to turn on and off, separately.
• Send these set variables to an arduino
  -The arduino will use this information to monitor and control the parameters
• Using an EC sensor, the arduino will measure the EC of the water.
• If the EC is too low the arduino will run a calculation and will signal peristaltic pumps to dispense a specified volume of nutrient solution into the reservoir.(I have a calculation for this already that can be used in the code). Will use two part nutrient solution so there will be two nutrient peristaltic pumps.
• Using a pH sensor, the arduino will measure the pH of the water.
• If the pH is too high(basic) the arduino will signal a peristaltic pump to dose an acidic solution in small amounts until desired pH is reached.
• If the pH is too low(acidic) the arduino will signal a peristaltic pump to dose a basic solution in small amounts until desired pH is reached.
• The arduino will switch on and off grow lights at times specified by the iphone app.
• The arduino will switch on and off water pumps at times specified by the iphone app.
  -The arduino will also monitor water level and send a notification to the iphone app if water level is too low.
