Week -2
1. the simulation shows a door bell with the help of a solenoid.whenever the swith is closed the switch is closed the battery will be get in connected with the solenoid which attracts the iron rod towards the coil and the bell will ring. in this we are using a pulse generator beacause for the activation of pulses and to on the switch.the time delay will depends on the delay that you give to the pulse generator.
2.the controlled temperature block takes the input signal from the signal builder block and gives it to the thermistore.the thermistor senses the temperature whenever the temperature crosses the beyond level the fans get on and otherwise the fans will be off.
