Note: Draw theschematic and code for each of the following question. All questioncarries equal marks.
1. Design heat controlsystem as follow.
Design a system tomaintain the temperature of the system at 37 degree celcius.Atemperature sensor is attached with the Arduino analog input. A fan(220 volts) and heater (220V) is placed in a room. If temperatureis greater than 37 degree, turn the fan on and if temperature isless than 37 turn on heater.
Take the temperaturereading after every 10 minutes.
*Hint: Use relay toturn on Fan and heater.Control the realy using Arduino.
