• Reporting the brightness of ambient light

You can view the values the Optical Sensor is reporting as a project is running on the _______.

• Dashboard on the VEX EXP Brain

• Field Tile

• VEXcode EXP Toolbox

• Help

Which of the following is a NOT possible use for the Optical Sensor?

• To drive forward until a wall is detected

• To make a decision based on the color of an object that is detected

• To report the brightness value of ambient light

• To repeat behaviors for a specified number of times

The [If then] block enables your robot to do which of the following:

• Drive forward for a specific distance

• Repeatedly check a condition

• Turn left 180 degrees

• Make a decision

If the Boolean condition is reported as _____ the blocks inside of the [If then] block will _____.

• FALSE; run

• TRUE; run

• TRUE; be skipped

• FALSE; be skipped

• Both B and D

To make an [If then] block check a condition multiple times, which of the following blocks can be added?

• [Drive for]

• [Forever]

• [Spin for]

• None, the [If then] block repeatedly checks conditions

How many times will the behaviors in this [Repeat] block be executed?

• 300

• 90

• 6

• 0

What condition will be checked next if the condition of the Optical Sensor detecting red is FALSE?

• The condition of the Bumper Switch being pressed.

• The condition of the Optical Sensor detecting green.

• The condition of the Optical Sensor detecting blue.

• The condition of the Touch LED being pressed.

What is the purpose of having multiple [If then] blocks in this project?

• To have the robot check if a button is pressed on the Brain and move the drivetrain based on the condition.

• To have the robot drive forward when the X button is pressed.

• To have the robot complete different actions when a color is detected with the Optical Sensor.

• To have the robot drive through a disk maze using the Bumper Switch.

In this project when the Optical Sensor detects _____ the robot will _____?

• Red; turn right 90 degrees

• Blue; drive in reverse 300mm

• Green; drive forward 300mm

• Red, drive forward 300mm

• Both the Red and Green commands shown will be executed
