The Complete Beginners Guide to Arduino - 2021 - Dot Matrix Display - Electronic Dice

This video tutorial guides viewers through creating an electronic dice using a dot matrix display. It begins with an introduction to the dot matrix display and the project setup. The instructor explains how to reuse code from a previous project and adapt it for the LED matrix. The tutorial covers defining binary patterns for dice faces, implementing LED control, and setting up functions. The 'throw the dice' function is explained in detail, including its logic and how it simulates dice rolling. The video concludes with final steps to complete the project, offering suggestions for housing the electronic dice in a project box.

What is the main advantage of using a dot matrix display over individual LEDs for the electronic dice project?

• It requires less power.

• It provides a more realistic dice appearance.

• It is cheaper to implement.

• It is easier to program.

Which component is connected to digital pin 5 in the hardware setup?

• The Pizzo

• The button

• The clock pin

• The data pin

How many elements are there in the two-dimensional array used to store the dice patterns?

• Four elements

• Six elements

• Eight elements

• Ten elements

What is the purpose of the LC shutdown command in the setup function?

• To turn off the LED control

• To set the brightness of the display

• To initialize the random number generator

• To ensure the device is powered up

What is the role of the random seed in the setup function?

• To generate different random numbers each time

• To ensure the button works correctly

• To initialize the LED control

• To set the initial brightness

What is the maximum brightness level set for the LED display in the setup function?

• 50% brightness

• 25% brightness

• 100% brightness

• 75% brightness

In the throw the dice function, what does the do-while loop ensure?

• The same dice face is not repeated consecutively

• The dice face is displayed for a fixed duration

• The sound is played continuously

• The display is cleared after each roll

What is the initial value of the delay in milliseconds in the throw the dice function?

• 5 milliseconds

• 10 milliseconds

• 1 millisecond

• 0 milliseconds

How does the throw the dice function simulate the dice rolling effect?

• By incrementally increasing the delay between face changes

• By displaying random numbers on the screen

• By changing the brightness of the LEDs

• By playing a sound continuously

Which function is responsible for handling button presses in the loop?

• throw the dice function

• button read function

• setup function

• LED control function
