Task One: Air conditioning (AC) control system
Design a simple AC control system that receives a signal from a digital thermometer sensor.
Depending on the room temperature, the signal will control the air conditioner to operate in
Heating, Ventilation, or Cooling modes.
The digital thermometer signal produces a 4-bit binary number proportional to temperature,
where 0000 represents 0 degrees and 1111 represents 48 degrees (so each binary number
represents a multiple of 3 degrees).
Consider the following specifications in your combinational logic circuit design:
Whenever the temperature is less than T₁, the AC should operate in Heating.
Whenever the temperature is greater than T2, the AC should operate in Cooling.
Whenever the temperature is between T₁ and T2, the AC should operate in Ventilation.
Where:
T₁ = 14 + (your last digit of your university ID) mod 4 degrees
T₂ = 17+ (your last digit of your university ID) mod 4 degrees
