We need to use the breadboard because:
The Arduino board can’t work without the breadboard
GND pins and 5V pins are limited
To increase the GNDs ports
None of them
What component do you need to use in Tinkercad to control the blinking of the LEDs?
Resistor
Arduino Board
Breadboard
Battery
Which of the following connections should you use for the LEDs in Tinkercad?
Anode connected to GND and cathode to Digital pin
Anode connected to Digital pin and cathode to GND
Both anodes connected to the battery
Both cathodes connected to the Arduino
To code the Arduino for the LEDs to blink, which function is essential to create a delay between the on and off states?
delayMicroseconds
delay
wait
pause
In Tinkercad, which block is used to make the LED turn on?
Set pin to LOW
Set pin to HIGH
Turn LED On
Set LED Active
To repeatedly blink an LED a specified number of times, which loop should you use in Tinkercad?
If statement
Repeat loop
While loop
For loop
These are the steps to create a blink effect: Setting the LED HIGH, waiting, setting LED LOW, then waiting again. Which of these actions should be inside the repeat loop?
Only the delay
The entire sequence (HIGH, wait, LOW, wait)
Only setting LOW
Only turning the LED on
Which block in Tinkercad allows you to define how many times the repeating action occurs?
Repeat until
Repeat with number
Repeat for each
Repeat always
When using a repeat with a condition, which block checks whether the condition is true or false?
Option 1 (Assuming Option 1 is the correct block shown in the image)
Option 2
Option 3
None of them
Which block would you use to change the delay time for the blinking during runtime?
What will happen if you set the repeat count to zero?
The LED will never blink
The LED will blink infinitely
The LED will turn on and then off immediately
The program will crash
The waiting that is used for turning the LED on:
10 seconds
1 second
10 millisecond
1 millisecond
This code makes the LED blink ………
fast then it slows down
slow then it becomes fast
the same way all the time
None of them
The loop that is used in the following code is running:
10 times
20 times
forever
None of them
In the following code, the LED will blink:
2 times then it will stop blinking
3 times then it will stop blinking
forever and it will not stop blinking
5 times then it will stop blinking
