It is possible to use the sensor for single light intensity read-
ings. Setting the light color to Red the sensor functions as a
Light Sensor. Using another light color (Green or Blue) can give
different results.
The sensor can be used to take readings of light intensity from
ambient or reected light. Any of the three colors can shine
when reading reected light.
You can use the sensor as a color lamp to control the individual
output colors (red, green or blue) and add personality to your
robot.
Select the View submenu on the NXT’s display. Select the color sensor icon and the
port where you have connected the sensor.
Hold the color sensor approximately
1 cm above the different colors on the
Testpad, and the NXTs display will
write the value and name of the color.
You can test the color sensor in different ways:
Connect the color sensor to the NXT.
Select the Try My submenu on the NXT’s display and test your
Color Sensor. You’ll get a fun reaction.
