+/*
+Developer: Christian Andresen
+
+Project name: Project Greenhouse
+
+Brief description:
+    Microcontroller observing the climate within a greenhouse, and displaying warnings/information as needed.
+    Sensors monitor light levels, as well as temperature and humidity.
+    To simulate an actual greenhouse, LEDs will be used in place of actual influences.
+
+Objectives:
+- Able to set controller location (Which section/greenhouse is it located in)
+- Able to open window at certain temperature tresholds (For 5 minutes)
+- Water plants at regular intervals (Twice a day)
+- Plants must have light for at least 12 hours. If weather is cloudy, artificial lights.
+- Testmode: Alternate time-tracking system, much faster than 24 hour system.
