Week -2

1.Make a Simulink model of Doorbell using solenoid block

Doorbell

Doorbell is an instrument which is used to indicate the presence of someone near our home gate, in the manner they need to indicate their their presence in the gate. The doorbell is operated in the manner of closed and open loop circuit so that we can get the ringing sound. To make it operated using the simulink model we need the following blocks namely,

Solenoid,Pulse generator, Battery,Switch,Scope,Ideal Translational Motion Sensor,Mechanical Translational Reference,Solver Configuration, Electrical Reference,Simulink-PS Converter and PS-Simulink Converter

To Make the doorbell model the Switch is needed for the Solenoid to get activated, the Switch is being given pulse using Pulse generator, Simulink-PS Converter is connected to the pulse generator to convert the simulink signal to physical signal. The Battery is used to give the power supply to the circuit. The two Scope is used, one to see the input signal and the another to see the output signal.Mechanical Translational Reference is given inorder to provide the ground for all the mechanical components.Electrical Reference is provided for the ground the electrical signals. The solver

The solver configuration specifies the necesery data for the simulink model to brgin the function.

the model is attached in the attachment with the results kindly find the attachment

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

1.0-10 sec temperature 293

2. 10-30 secs temperature 300

3. 30-50 secs temperature 296

and you can see these details in plot basis in signal builder block where the input is inserted with these signals.

the results are being added in the attachment kindly find the attachment
