Week -2

Q-1

Doorbell

Took a pulse generator to create a signal, which gives to a manual switch connected with a battery and a solenoid when switch keeps closed it creates electromagnetic effect in solenoid, and results in change in position of plunger which observed by translational motion sensor and finally displayed in scope.

Q-2

It is a thermistor controlled fan, first of all I used

Signal builder to create signal as per given time frame and temperature, then with the help of Simulink-PS converter I connect controlled temp source to control temp as reqd. therefore a thermistor connected for the measurement of temp, which further connected to voltage sensor and ON/OFF Switch (for ON/OFF switch we give threshold value to input .012 voltage at the temperature of 25 deg), which further connected to voltage source to give voltage to DC motor when switch is ON and fan start rotating.
