EV3 Block Coding Mastery Flashcard

Front

What is the purpose of a loop in EV3 block coding?

Back

To execute a block of code multiple times

Front

Which loop structure would you use to repeat a set of instructions a specific number of times in EV3 block coding? Options: Forever loop, While loop, For loop, Until loop

Back

For loop

Front

What sensor can be used in EV3 block coding to detect color?

Back

Color sensor

Front

How can you make a program wait for a touch sensor to be pressed in EV3 block coding?

Back

By using a loop that checks the touch sensor's state

Front

What does the "break" block do inside a loop in EV3 block coding?

Back

Exits the loop immediately

Front

Which sensor is NOT typically used to control robot navigation in EV3 block coding? Gyro sensor, Color sensor, Sound sensor, Ultrasonic sensor

Back

Sound sensor

Front

In EV3 block coding, how can you make a robot move until it detects an object in front of it?

Back

Use a loop with an ultrasonic sensor condition.

Front

What is the function of the "Wait" block in EV3 block coding?

Back

To delay the program for a specific amount of time, to wait for a specific sensor condition to be met, and to help sequence your coding.

Front

How can loops be nested in EV3 block coding?

Back

By placing a loop inside another loop

Front

Which of the following is true about using sensors in EV3 block coding?
Options:
Sensors can only be used inside loops,
Sensors can trigger events that start or stop loops,
Only one sensor can be used in a program,
Sensors are not necessary for robot movement

Back

Sensors can trigger events that start or stop loops
