Week -2

Doorbell system has been implemented using a Solenoid,a Pulse Generator and Battery for Power Supply.Solenoid plunger movement has been implemented using Ideal Translational Motion Sensor.As per the given condition that the Switch will be closed for 2 seconds, the Time Period of Pulse Input has been set at 4 seconds.After simulation the graphical version of plunger movement has been checked and found to be in conformity with the initial conditions specified in the given problem.

The Thermistor challenge has been implemented using a Thermistor Block,Controlled Temperature Source,Signal Builder,DC Voltage Source,Voltage Sensor and Current Sensor.

In the output side for turning the fan ON/OFF a Switch has been used.While simulating this model some errors have been encountered.The errors can be attributed to initial conditions triggered by the Solver Configuration as well as the Thermistor wherein the message being displayed by the system is 'Temperature must be greater than zero'.So I feel that some fine tuning of this particular model is required which I could not complete myself due to my own limitation.
