What is the purpose of the serial monitor in the Arduino setup?

• To display the Arduino's power usage.

• To show the sensor readings for calibration.

• To connect multiple Arduinos together.

• To program the Arduino board.

How can you determine the threshold values for activating LEDs based on sensor input?

• By consulting the Arduino manual.

• By using a fixed set of values.

• By using trial and error with the serial monitor.

• By guessing the values.

What is the role of the 'pinMode' function in the Arduino code?

• To initialize the Arduino board.

• To write a voltage to a pin.

• To read the voltage from a pin.
