 ## Design & Architecture
 ------------------------------------------------------------------------
 
+In order to accomplish the smart water heater, the project will be in steps. The first step includes the smart water temperature sensor. It will measure the temperature and it will indicate it on the screen. The second step will be the smart water heater where the temperature will rise and the temperature sensor will measure the new temperature.
