What is the purpose of the NPN BJT transistor? Explain how changes in the photoresistor's resistance are measured by the Arduino. Which pins on the Arduino are used to implement the I2C communication protocol? SCL: SDA: In the code for the sensor, why does the value read from the ADC have to be divided by 4 before being transmitted? In the code for the sensor, what changes would you need to make to the program to send the sensor readings every 2 seconds? In the code for the actuator, what is the purpose of the map function in line 24? During simulation, why are the values shown in the sensor and actuator's Serial Monitors not the same? What is the oscilloscope displaying? What does the value displayed by the voltmeter represent? How is the intensity of the light bulb controlled?

a) An analog-to-digital converter (ADC) measures voltages in the range of 0 to 25 V and has 12-bit accuracy. What is the smallest voltage step that the ADC can resolve? b) A ramp-type ADC system uses a 10 MHz clock generator and a ramp voltage that increases from 0 V to 1.25 V in a time of 125 ms. Determine the number of clock pulses counted into the register when V = 0.9 V, and when it is 0.75 V. c) If 3.45 V is applied to a 4-bit successive-approximation-type A/D converter which has a reference voltage of 5 V, what will be the digital output of the ADC? d) An 8-bit ADC is converting a temperature signal which has a measuring range of 0 °C to 800 °C. Calculate the resolution of the temperature-measuring instrument. e) Determine the number of output bits required for an ADC so that quantizing error is less than 1%. f) The resistance of a thermistor is 800 Ω at 50°C and 4 kΩ at the ice point. Calculate the characteristic constants (A, B) for the thermistor and the variations in resistance between 30°C and 100°C.
