Activity 2: Master Driver • Lesson 3: How Does a Touch Sensor Work? Activity 3: Music by Touch: Programming Robot Tactile Sensors to Play Sounds • Lesson 4: How Does a Sound Sensor Work? Activity 4: Control Using Sound • Lesson 5: How Does a Color Sensor Work? Activity 5: Follow the Light • Lesson 6: How Does an Ultrasonic Sensor Work?. Most patients who benefit from biofeedback are trained to relax and modify their behavior. At the center of the cylinder is a sensor that splits light bounced from the document into three beams. When using reflectance-type or break-beam light sensing, controlling the sensor's own illumination source is a good strategy.
