Automatic Dog (or cat) Treat Dispenser with Arduino

The video tutorial explains how to create an automatic dog treat dispenser using an Arduino. It covers the mechanical design, including the use of popsicle sticks and cardstock, and the circuit setup with components like a potentiometer and LCD screen. The tutorial also provides a detailed guide on programming the Arduino to dispense treats at specific times, using a real-time clock and various sensors for customization.

What is the primary function of the servo motor in the dog treat dispenser?

• To alert the owner with a buzzer

• To detect the presence of the dog

• To rotate the compartments to dispense treats

• To display the time on the LCD screen

Why is it recommended to use sturdier materials instead of paper for the dispenser?

• Paper is too expensive

• Paper is not durable enough for pets

• Paper is difficult to assemble

• Paper is not environmentally friendly

What role does the potentiometer play in the circuit?

• It controls the buzzer volume

• It powers the servo motor

• It adjusts the contrast on the LCD screen

• It resets the Arduino

Which component is optional if you do not need a time readout?

• Potentiometer

• Servo motor

• LCD screen

• Buzzer

Which sensor can be used to detect a magnetic tag on a pet's collar?

• Magnet sensor

• Distant sensor

• Motion detector

• Microphone

How can the treat dispenser be customized for different behaviors?

• By altering the LCD screen

• By using different sensors with the Arduino

• By changing the servo motor

• By modifying the potentiometer

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

• To display messages on the LCD

• To initialize pin modes and set initial conditions

• To power the Arduino

• To loop the program continuously

What is the purpose of the real-time clock in the Arduino project?

• To control the servo motor speed

• To keep track of time for dispensing treats

• To power the Arduino

• To adjust the LCD contrast

How does the code ensure the servo motor moves smoothly?

• By reducing the number of compartments

• By increasing the power supply

• By using a while loop to increment the angle gradually

• By using a single servo write command

What is the significance of the angle increment variable in the code?

• It determines the speed of the servo motor

• It defines the angle by which the servo rotates each time

• It sets the initial position of the servo

• It controls the brightness of the LED
