You have built a Ferris Wheel. You need it to stop when a particular sound is played. How will you use Broadcast and Recieve blocks to achieve this?

  2 - When "Stop" is received, stop the motor.

• When sound plays, stop the motor.

• 1 - When sound plays, send "Stop" message.

  2 - When "Sound" is received, stop the motor.

• 1 - When sound plays, send "Stop" message.

  2 - When "Stop" is received, start the motor.

When the message "Start" is received, two actions happen simultaneously - the motor starts moving and the lights flash. This is an example of:

• Parallelism in coding

• Loops in coding

• Events in coding

• Messages in coding

By always setting the motor position to "0" before starting the ride, you can make sure that each time the Ferris Wheel turns, the seat stops at the exact same place for riders to embark.

• True

• False
