2. Overview: This lesson explores the View Mode capability of the NXT and uses this to demonstrate electrical circuits using the NXT electronic components. Objectives: Students will be able to: 1. Display the value of a sensor on the NXT screen 2. Measure the value of a sensor under various test conditions 3. Interpret measured sensor values

6. (3:30) This NXT Viewing Sensors video covers the NXT brick's View Mode capability utilized in this lesson. The video also goes on to explain calibration and other capabilities beyond the scope of the NXT Test Circuits lesson. Viewing Sensors video http://stemrobotics.cs.pdx.edu/node/441

7. Worksheet View Mode Name:_________________________ Period:___ Date:________ Score:_____/14 1.(2 pts) Connect the touch sensor and select “Touch” mode. What do you notice? What does the displayed value represent? 2.(3 pts) Connect the light sensor and select “Reflected Light” mode. What do you notice? Pass the sensor over different surfaces and at different heights. What is does the displayed value represent? Repeat with the “Ambient Light” mode. Are they different? If so, how? 3.(3 pts) Connect the ultrasonic sensor and select “Ultrasonic inch” mode. What do you notice? What is does the displayed value represent? Use a variety of objects of different size and texture. Repeat with the “Ultrasonic cm” mode. Are they different? If so, how? 4.(3 pts) Connect the sound sensor and select “Sound dB” mode. What do you notice? What is does the displayed value represent? Repeat with the “Sound dBA” mode. Are they different? If so, how? 5.(3 pts) Connect a motor (with an axle and wheel) and select “Motor Rotations” mode. What do you notice? What is does the displayed value represent? Repeat with the “Motor Degrees” mode. Are they different? If so, how?

8. Review Question 1 In “View Mode”, with a motor in the circuit, what two types of information can be read from the LCD screen?

9. Review Question 1 In “View Mode”, with a motor in the circuit, what two types of information can be read from the LCD screen? Number of full rotations, or total number of degrees of rotations of an NXT motor
