Forward Until Dark Light Sensor

Touch Sensor

The Touch Sensor detects physical contact with the

orange trigger, and returns a SensorValue of 1 if it is

pressed in, or 0 if it is not.

Ultrasonic Sensor

The Ultrasonic (sometimes called Sonar) Sensor sends

out pulses of sound and measures the time it takes for

the sound waves to bounce off an object and return.

Since the speed of sound is known, the sensor calculates

the distance based on the time, and reports the distance

in centimeters as its SensorValue

In this lesson, you will learn how the Light Sensor works, and how its feedback compares to

the Touch and Ultrasonic Sonar sensors.

Detects:

Feedback:

Typical use:

Sample code:

Physical contact

0 if unpressed, 1 if pressed

Bumper

while (SensorValue(touchSensor) == 0)

will run the while() loop as long as the

touch sensor is not pressed.

Detects:

Feedback:

Typical use:

Sample code:

Distance to object

Range to object in centimeters (1-250)

Obstacle detection and avoidance

while (SensorValue(sonarSensor) > 25)

will run the while() loop as long as there

is no object detected within 25 cm.
