Arduino for Beginners - 2022 Complete Course - Activity 03 - Solution

The video tutorial explains how to set up an LED and button using a microcontroller. It covers initializing pins, reading button states, and controlling the LED based on button input. The tutorial includes compiling and uploading the code, followed by testing the setup to ensure the LED responds correctly to button presses. The activity demonstrates combining input and output components to create a responsive program.

What is the purpose of using the define statement in the setup of the LED and button?

• To configure the pins as input or output

• To assign a constant name to the pin numbers

• To set the initial state of the pins

• To allocate memory for the pins

In the loop function, what does the digitalRead function do?

• It writes a high or low value to a pin

• It reads the current state of a pin

• It initializes the pin mode

• It compiles the code

What happens to the LED when the button is pressed according to the code logic?

• The LED changes color

• The LED turns on

• The LED turns off

• The LED blinks

What should you ensure before uploading the code to the board?

• The LED is removed

• The board is correctly connected

• The button is pressed

• The board is powered off

What is demonstrated by combining input and output components in this activity?

• A basic programming error

• A smart program that makes decisions

• A complex hardware setup

• A simple circuit design
