Answers:

PULSE GENERATOR: It is used to give the input signals and time is set for a period of every 2sec.
SIMULINK PS CONVERTOR: It is used to convert input signals as a physical signal.
SWITCH: If the external physical signal ps is greater than threshold value then switch is closed, otherwise switch is open.
BATTERY: The input and +ve and-ve terminals of a battery is connected to +ve and -ve terminals of the system.
SOLENOID: When a maximum load is applied to a plunger, the metal strip in the plunger gets completely compressed ans setes out the plunger to zero when load is removed.
IDEAL TRANSLATIONAL MOTION SENSOR: The positon and velocity is been calculated with respect to R & C ports.
SOLVER CONFIGURATION: It is used to set solver values for simulation.
ELECTRICAL REFERENCE: It is given for electrical circuits.
MECHANICAL ROTATIONAL REFERENCE: It is given to mechanical circuits and fixed to ground.
PS SIMULINK CONVERTER: It is used to convert physical signal as a simulink signal.
SCOPE & DISPLAY: It is used to display the output.

CONCLUSION:

pulse generator is connected to a switch, power is driven by the switch from the battery ,here solenoid acts as electromagnet which consists of a metalic strip & gets compressed when a force is applied to it and then hits the bell and gives a sound for every 2sec of time period and sets to zero when load is removed.

OUTPUT:

From the graph we can absorb the position of velocity for simulink model of Doorbell using solenoid block.

2.THERMISTOR TO SENSE TEMPERATURE AND HEATER TO TURN OFF & ON THE FAN:
