Arduino Dog Treat Dispenser Quiz

What is the primary function of the automatic dog treat dispenser?

• To monitor the dog's health

• To play music for the dog

• To track the dog's location

• To feed the dog automatically at specific times

What material is suggested for constructing a durable treat dispenser?

• Plastic

• Paper

• Cardboard

• Glass

Which component is used to adjust the contrast on the LCD screen?

• Resistor

• Diode

• Capacitor

• Potentiometer

What is the advantage of using an Arduino in this project?

• It is waterproof

• It is cheaper than other microcontrollers

• It is compatible with a wide variety of sensors

• It requires no programming

Which library is necessary for controlling the servo motor?

• Wire Library

• SPI Library

• Servo Library

• Liquid Crystal Library

What is the purpose of the setup function in the Arduino code?

• To display messages on the LCD

• To initialize variables and set pin modes

• To run the main loop of the program

• To power the Arduino board

How does the code ensure smooth servo motion?

• By using a single Servo write command

• By using a while loop to increment the angle gradually

• By using a for loop to set the angle

• By using a delay function only

What happens when the new angle exceeds 180 degrees?

• The servo resets to the initial position

• The servo stops moving

• The servo reverses direction

• The servo continues to rotate

What is the purpose of the 'wait for button press' feature in the code?

• To pause the program indefinitely

• To change the servo speed

• To turn off the Arduino

• To allow manual reset of the dispenser

Which function is used to update the LCD screen with the current time?

• updateTime()

• displayTime()

• getTime()

• printTime()
