Week -2
AIM:
To create the Simulink model of doorbell block for the situation where the switch is closed for 2 seconds and then released to observe the physical movements of the plunger.
A solenoid is an electromagnetic device consisting of coils and wires, the housing, and the plunger (armature) which is moveable. Whenever the electrical input is given, it forms the magnetic fields which draw the plunger in. So basically it is the conversion of electrical energy into mechanical energy.
PROCEDURE:
The pulse generator generates the continuous pulses of a regular given time interval which is given to switch through the Simulink - PS converter.
One part of the SPST (single pole single through) switch is connected to the battery and the other is connected to the solenoid.
The other part of the battery is connected to the solenoid with the ground (electrical reference) with solver configuration.
The solenoid is connected with the ideal transformation motion sensor with mechanical translational reference and the same connection to the scope via PS-Simulink converter to view the output
WEEK 2 - CHALLENGE 2:
AIM:
Using a thermistor to sense the temperature of a heater & turn on or turn off the fan when the temperature source is 20 °C from 0 to 10 seconds, 27 °C from 10 to 30 seconds, 23 °C from 30 to 50 seconds assuming fan condition is ON only when the temperature is above 25 °C.
FAN CONTROLLED BY THERMISTOR:
The thermistor is the temperature-controlled device that senses the temperature and changes the resistance values accordingly. PROCEDURE:
Signal builder block is used to give the input as per the given requirement given.
A controlled temperature source represents the ideal source of thermal energy that maintains controlled temperature differences regardless of heat flow rate.
One part of the controlled temperature source is connected to the thermistor and the thermistor is connected to the resistor.
The resistor is connected to the voltage sensor which is used to convert the voltage measured between two points into the physical signal.
