Combine LEDs and Buttons - Work with Multiple Objects

The tutorial guides users through creating a program that combines push button and LED functionalities using Arduino. It covers setting up the program, defining pin numbers, creating and initializing objects, and writing logic to control LED behavior based on button presses. The tutorial concludes with testing the code and observing the LED responses.

What is the primary goal of the new program introduced in the tutorial?

• To create a new LED class

• To write a program with only one LED

• To combine LED and push button functionalities

• To design a new hardware setup

What is the first step after saving the new program?

• Restart the Arduino IDE

• Define the pin numbers

• Include the LED and Push Button classes

• Go to the sketch folder

Which of the following is NOT a pin number defined for the LEDs?

• 11

• 9

• 8

• 10

What is the purpose of the init function in the setup?

• To write pin modes

• To create new objects

• To initialize the LED and button objects

• To define pin numbers

What happens when the button is pressed according to the program logic?

• Only the green LED turns on

• The yellow LED turns on

• All LEDs turn off

• The red and green LEDs turn on

Which LED is turned on when the button is not pressed?

• Yellow LED

• Green LED

• Red LED

• All LEDs

What is the main advantage of using classes in this program?

• It reduces the number of lines of code

• It makes the code more complex

• It allows for independent behavior of objects

• It eliminates the need for a setup function
