Arduino OOP - 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, including necessary libraries, defining pin numbers, creating and initializing objects, and implementing logic to control LED behavior based on button states. 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 develop a new Arduino IDE

• To combine LED and push button functionalities

• To create a new LED class

• To design a new hardware setup

Which files need to be included in the program to use the LED and push button classes?

• LED.cpp and PushButton.cpp

• LED.h and PushButton.h

• PushButton.h and PushButton.cpp

• LED.h and LED.cpp

What is the purpose of defining pin numbers in the program?

• To configure the power supply

• To set the voltage levels

• To identify the pins for LEDs and push button

• To initialize the Arduino board

How does the init function simplify the setup process?

• By creating multiple objects

• By eliminating the need for pinMode

• By defining the pin numbers

• By automatically uploading the code

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

• The red and green LEDs turn on

• The yellow LED turns on

• All LEDs turn off

• The green LED turns off

Which LED remains on when the button is not pressed?

• All LEDs

• Yellow LED

• Green LED

• Red LED

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

• It allows for faster execution

• It makes the code more readable and organized

• It reduces the number of lines of code

• It simplifies the hardware setup
