Question#4: [15 Pts]

We expect to design a project for controlling the temperature inside a room based on a temperature sensor and fun. The required components are shown below. The motor of the fun is assumed to be controllable by a PWM signal.

Wire the temperature sensor and the fun motor to the Arduino Board and justify your wiring

The temperature sensor provides 750 mV at 25 degrees centigrade and 500 mV at 0 degree centigrade. Calculate the output scale factor of this sensor:

Given that the Arduino Uno board Analog-Digital-Converter works with 10 bits. How many values of temperature can be read from the temperature sensor? Justify your answer.

Cite all digital pins number in which the fun can be connected and justify

analogRead(Analog_Pin_Number);

analogWrite(PWM_Pin_Number, value);

value varies between 0 for 0% duty cycle and 255 for 100% duty cycle.
