LIGHT SENSOR

The Light Sensor is one of the two sensors that give

your robot vision (the Ultrasonic Sensor is the other).

The Light Sensor enables your robot to distinguish

between light and dark. It can read the light intensity

in a room and measure the light intensity of colored

surfaces.

Detecting ambient (surrounding) light

Test the Light Sensor's ability to read ambient light by

measuring the light level in different locations of the room.

For example, ﬁ rst hold the sensor against the window. Then

hold it under the table. Watch how the readings differ.

Test it!

You can test the Light Sensor in different ways:

Connect the Light Sensor to the NXT.

Select the View submenu on the

NXT's display. Select the Light

Sensor icon and the port where you

have connected the sensor.

This is what your eyes see.

This is what your robot will see,

using the light sensor.

Suggestions for use

You can use the Light Sensor to make a burglar

alarm robot: when an intruder turns on the light

in your room, the robot can react to defend your

property. You can also use the Light Sensor to

make a line-following robot or a robot that can

sort things by color.

Hold the Light Sensor up to the different colors on the test pad and see

the different readings.

Select the Try Me submenu on the NXT's display and test your

Light Sensor. You'll get a fun reaction.
