+* The below program is developed beased on IOT assessment 3 requirements.
+* The below program reads temperature for ever 5 sesonds
+* and when the temperature goes higher than 26 degree celcius the progam shuts down the
+* processor for 5 seconds and comes back again. The processor can also be make active when a
+* switch is pressed.
