Question

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?
