Week -2

Door bell:-

The given input as the time period for 2sec in the pulse generator to open & close the switch. when the switch is closed the solenoid block recevives electrical power from the battery and pluger moves from part R to C to hit the bell and produce sound.

physical movement of the pluger is observed by using translational motion sensor and physical output is converted into simulink output model is displayed in the scop.

Thermistor:-

Temperature source -20 from 0 to 10sec, 27 from 10 to 30sec, 23 from 30 to 50 sec

we have to build an input signel based on from above co-ordinates.

fan condition - ON if temperature above 25 degrees, other wise it will be in OFF condition.

From 0-10 sec fan is OFF because the temperature is 293k which is below 293k, after 10 sec it goes to 300k,so fan will turn ON because temperature exceeds 293k. after 30 sec fan will turn OFF because temperature goes 293k and less than 298k.
