What is the first step in connecting the soil moisture sensor to the Arduino?

• Connecting the sensor to the ground.

• Connecting the sensor to the power supply.

• Connecting the sensor to the comparator circuit.

• Connecting the sensor to the digital pin.

Which pins on the comparator circuit are used for power and ground connections?

• To power the Arduino

What range of values can the Arduino read from the soil moisture sensor?

• 0 to 1023

• 0 to 2048

• 0 to 512

• 0 to 255

What happens to the sensor reading when it is placed in a dry environment?

• The value fluctuates randomly.

• The value decreases to around 0.

• The value remains constant.

• The value increases to around 1023.

What should you do if the sensor reading is too high, indicating dry soil?

• Reset the Arduino.

• Remove the sensor.

• Add more water to the soil.

• Ignore the reading.

What can you use to automate the watering of a plant based on the sensor reading?

• A fan

• A LED light

• A buzzer

• A water pump
