Week -2

1. Made a simulink model of doorbell with solenoid, in this at 3 sec the switch is turned ON for 2 sec, at 5th second the plunger gets oscillated, due to damper the oscillation is weakend and at 6.5 sec it becomes steady.

2. Made a simulink model for temperature sensing fan, in this fan is a DC motor and the required input of temperature variation is given, the reference voltage across the resistor got as 9.09V at 25 celcius, so when the voltage rises above the reference voltage the fan turns ON, this is shown in the output plot.
