Arduino Force Sensitive Resistor Quiz

What happens to the resistance of a force sensitive resistor when it is pressed?

• It remains constant

• It fluctuates randomly

• It decreases

• It increases

Why are force sensitive resistors not suitable for precise force measurements?

• They are not compatible with Arduino

• Their resistance changes with contact area

• They require complex circuits

• They are too expensive

What is necessary to measure the output of a force sensitive resistor with an Arduino?

• A direct connection to the Arduino

• A voltage divider circuit

• A digital multimeter

• A special Arduino shield

In the Tinkercad simulation, what indicates that the force on the sensor is increasing?

• The voltage decreases

• The LEDs turn off

• The sensor stops working

• The voltage increases

What is the purpose of using the 'analogRead' command in the Arduino code?

• To turn on the LEDs

• To read the sensor value

• To connect to the internet

• To power the Arduino

How does the Arduino convert the sensor's voltage reading?

• Into a percentage

• Into a frequency

• Into a number between 0 and 1023

• Into a binary code

What is the role of the 'serialPrint' command in the Arduino code?

• To display the sensor value on an LCD

• To print the sensor value to the serial monitor

• To control the brightness of LEDs

• To adjust the sensor's sensitivity

What can be adjusted to affect the range of readings from the force sensor?

• The value of the series resistor

• The type of LEDs used

• The length of the wires

• The Arduino's power supply

What is a potential application of a force sensitive resistor in an Arduino project?
