Lawn sprinkler design - design the controller for a lawn sprinkler system. the controller accepts three inputs: start, dryness, and rain. it produces two outputs: on, and flow. the description of input/output signals is as follows: • start = 1. start sprinkler in the morning (on=1), if and only if it is needed. • dryness : is a 2-bit input: 00 = too dry, 01 = dry, 10 = wet, and 11 = fully watered. • rain = 1. it is raining and the sprinkler should not be turned on. • on = 1. turn on the sprinkler system. • flow is a 2-bit output which controls the flow of water: 11 = maximum flow, 10 = medium flow, 01 = drip, and 00 = no flow. the sprinkler system is turned on (set on=1), if start =1. the lawn is not fully watered and it is not raining. the output flow should be "maximum" when the lawn is too dry, "medium when it is dry, and "drip" when it is wet. the sprinkler should be turned off when the lawn is fully watered. design this controller using minimum logic for every output. draw the schematic of the design using gates.
