- LabVIEW Tutorial
- Code up examples in LabVIEW for slides 11, 14, 27, 31, 36, 38, 41. Put each one in a separate VI and demo to me or T/A.
- Configure LabVIEW options as shown in slides 15-17
- Exercises 1,2,3
- Homework 3 - Finish Exercises
- Assign Project1 - Simulation
- Homework 4 - Finish ComputeAngle.vi (in Project1 -> RoboticSensing.zip -> micSourceLocator.lvproj -> My Computer -> ComputeAngle.vi) and ComputeIntersection.vi
