• The second condition of the Brain Down button being pressed will be checked.
• The [spin] block
• The [wait until] block
• The [stop motor] block

This project is running and the robot turned right. What condition is true?

• The Check button is pressed

• The Check button is NOT pressed
• The Up button is NOT pressed

Which of the following is the best pseudocode for this project?

• If the Brain Up button is pressed (TRUE) and the Brain Down button is pressed (TRUE), lower the arm. If the Brian Up button is pressed (TRUE) and the Down button is released (FALSE), raise the arm. If the Brain Up or Down buttons are pressed (TRUE), stop the Arm Motor.
• Raise the arm when two buttons are pressed. Lower the arm when one button is pressed. Turn right when no buttons are pressed.
• If the Brain Up button is pressed (TRUE), then spin the arm up. If it is released (FALSE), then check if the Brain down button is pressed. If the Brain Down button is pressed (TRUE) spin the arm down. If it is released (FALSE) then stop the arm.
• Use the Check, Up, and Down buttons as a UI

Which of the following is NOT a type of User Interface?
