not done

Today, we fixed the automation system. We altered the code by utilizing the millis function instead of delay so that the loop is not broken. Therefore, the button now successfully activates and deactivates the automatic watering system.

In addition, we made a container for our electronics so they do not get wet. Now, we will think back to biomimicry and design a new house that better mimics the Giant Sequoia tree.
