EV3 Sensor Functionality and Usage

The video tutorial covers the compatibility of EV3 Basic with various sensors, including NXT and DV3, and explains how to use third-party sensors. It details the conventions for attaching sensors to ports and setting sensor modes. The tutorial provides examples of programming with sensors, including reading percentage values and raw data. It also discusses advanced sensor readings, handling multiple outputs, and special cases like IR beacon and RGB mode.

Which ports are recommended for connecting a touch sensor and a gyro sensor on the EV3?

• Port 4 and Port 1

• Port 1 and Port 2

• Port 3 and Port 4

• Port 2 and Port 3

What is the correct method to set a sensor mode in EV3 Basic?

• sensor.changeMode

• sensor.modeSet

• sensor.setMode

• sensor.doSetMode

How can you obtain a percentage value from a sensor in EV3 Basic?

• sensor.readValue

• sensor.getPercent

• sensor.readPercent

• sensor.valuePercent

What happens when the touch sensor button is pressed in the example program?

• The robot moves forward

• A 500 Hz tone plays for 2 seconds

• The robot stops

• The sensor mode changes

What is the best practice for obtaining accurate distance readings from the IR sensor?

• Use transparent objects

• Use dark-colored objects

• Use light-colored objects

• Use reflective surfaces

What is the purpose of the 'read raw value' function in EV3 Basic?

• To set the sensor mode

• To read percentage values

• To change the sensor port

• To obtain non-percentage values like color codes

Which parameter is NOT required for the 'read raw value' function?

• Port number

• Array of raw results

• Sensor type

• Index number

In which mode does the infrared sensor return two values?

• Mode 4

• Mode 3

• Mode 2

• Mode 1

What does the color sensor return in Mode 4 RGB?

• A single color code

• An array of three values for red, green, and blue light intensity

• A percentage value

• A distance measurement

Which element in the array represents the intensity of green light in Mode 4 RGB?

• Element zero

• Element one

• Element three

• Element two
