Design and analyse of a circuit which turns a DC motor at aspeed which is proportional to how much a temperature is away froma set temperature, and turns:
Clockwise when temperature is greater than (say) 25 degreesC.
Anticlockwise when the temperature is less than (say) 20 degreesC.
Such a circuit might be used to regulate the temperature of aroom by turning a ceiling fan to move warm air in/out of that room(using the roof cavity).
