-- Description: Sets the type of plant according to its
--              preferred soil moisture levels so watering 
--              suggestion can adjust according to type:
--              
--              - Dry (SW0 = 1) 
--                   Plant prefers dry soil
--                   Ex: succulents
--              - Avg.(SW1 = 1) 
--                   Plant prefers moderately moist soil
--                   Ex: everything else
--              - Moist (SW2 = 1) 
--                   Plant prefers moist soil
--                   Ex: ferns
--
--              The selected setting is displayed in the 7-segment display.
