Week -2

1.Make a Simulink model of Doorbell using solenoid block.

above graph shows output of door bell simulation. when from plus generator gives signals that signal can converted in physical signal that given to the switch and for on and off reason.and plus generator set the value of amplitude 1 and time period 4 second and plus width 50 % and solenoid damper value will change to 5 then i will get output shown above

2.Use a thermistor to sense the temperature of a heater & turn on or turn off the fan

Above figures the thermistor to sense the temperature of a heater simulation model.

Will signal builder block will connect to control temperature source and that signal given to thermistor and that can connected to voltage sencer and in Between voltage source switch is connected after that scope contacted
In thermistor we will set the temperature if 25°c then fan get turn on if not fan get off and out put shown above
