5. Applications in EG101 l LAB 3: Microphone l LAB 7: LabVIEW l LAB 8: Vibrations, Waves and Spectra l LAB 10: Fiber Optics l TimeFreq l TwoChan l Filter l Record l Playback

6. Sample Interfaces

7. Remote Communication l Internet l Control Devices –Robotic Arm –Bridge

8. Graphics-based vs. Text-based GC++

9. Virtual Instruments (VIs) Appearance and operation imitates actual physical instruments

10. Front Panel and Diagram Panel

11. Tools

12. Front Panel Controls Terminal in diagram panel represents front panel object in source code

13. Controls and Indicators Two types of objects in front panel

14. Color Representation

15. Objectives l Learn basic, introductory commands l Input data (voltage) l Create two programs

16. Program 1: Calculator l Input –Keyboard –Input/Output board l Switch: 3 operations l 3 LEDs l 2 numeric controls l 1 indicator l Switch for input data l Case statement

17. Program 2: Voltmeter l Input from I/O block (±5 volts) l 7 LEDs: 7-segment display rounded to nearest integer l 1 negative sign LED l Case statement: control different combinations

18. LabVIEW Proficiency Test l 25-segment LED display with corresponding cases l 2 switches –binary-to-decimal –decimal-to-binary (inoperative) l Control l Warning function First 5 non-repeating letters and #s of name (last, first) and ID

19. Conclusions l Advantages –Saves money/space –Unlimited customized applications l More help –LabVIEW manuals –Help Team report Include: l Front/Diagram panels of both programs l Brief written explanations of implementation
