Air conditioner water recycling with an Arduino

Hello everyone! As you may know California is in a severe Drought along with many of the other states in the U.S. To help with

conserve water we have been saving water using a bucket when we do our dishes but we decided to take it to the next level! 

The airconditioner drys the air before it sends it into the house and therefore there is a condensation line that produces a little bit of water. 

The water is cold and clear and even though it may be potable we have not decided to find out. However, we have come up with a little 

system that captures the water in an old tuberware container and then pumps it into a 5 gallon bucket with an arduino, a relay control module,

and a small pump from Harbor Freight Tools. The code is relatively simple. It is just the standard arduino blink code with a couple of the settings

reveresed as well as longer delay times.
