Code Enabling and disabling the entire
operation through INT1 external interrupt
Automatic and manual operationFor controlling the motor PWM
concept is used i.e. varying duty cycle generation according to temperature.
Simulationlets take the output of ADC as
02H=00000010BFrom ttable value of temperature is 26
degree centigrade, corresponding hex code for 7 segments are,6D,5F,respectively.Offdelay=16*5+6=86,ondelay=100-86=14.. Duty cycle= 14%
Now if temperature value is 48 centigrade, offdelay=10*5+2=52, on delay=100-52=48, duty cycle increased to 48%. Hence motor speed will increase.

Hardware Implementation
ApplicationIn appliances power consumption
can be controlled. Eg. Air conditioners
In computers, it can be use to cool the processor
In institutes, Firms industries etc..
ConclusionThe problem statement is implemented
Hardware part is halfway implemented.
Through simulations and after running the code in IDE abstract is verified.
