    this is not very helpful. we already know about the sensors

Sound sensor - 4 views

  • Both LEGO™ NXT sound sensors were placed at the same distance from the speaker. A very simple LabVIEW NXT toolkit was run in debugging mode, in order to display the values on the PC screen and keep the NXT alive (Fig. 3). The frequency and the signal amplitude were gradually changed and the sensor readings were noted manually and entered into an Excel-file and also into a LabVIEW 3D-graph program (that we do not reproduce here). (Fig. 4 and 5) show the different graphs in 3D for the frequencies 100..1000Hz.

    The following documents contain information that you might find helpful as you use the LabVIEW Datalogging and Supervisory Control (DSC) Module. You must install the PDFs to access them from this help file. You must have Adobe Reader 6.0.1 or later installed to view or search the PDF versions of these manuals.

    we could use this logic, when the sound sensor detects the sound indicating the start of the race that would be the starting condition for the program ps. i know that we do not use the same programming as in the picture

    But what if people are speaking? you would have to set it to a certain frequency.

  • 3. In case the lighting in the room changes, could you program your line follower to re-calibrate the light sensor when you push a button?

    this would be a rather complicated idea for our robot but we should figure out a way to have more weight like this one so it stays on the ground. we would need to lower the nxt brick so it does not tip

Learn LabView: Programming LabView - Shift Register - 3 views

  • As you move forward with LabView programming, you will see that most design patterns are impossible without the shift register. Anytime you are trying to keep track of something in a loop, you will need to use one.
  • The shift register is a key element of LabView programming. It allows looping structures, such as the For and While loop, to carry over values from one iteration into the next. This can be extremely powerful in allowing the developer to build up arrays of information, or retain state information about a program running in a loop.

  • Wall-following is a simple maze algorithm you might have learned as a child. All you do to solve a maze using this algorithm is keep your left hand on the left wall (or your right hand on the right wall) and just follow it along until you exit the maze. It's easy to see that this algorithm always works if the maze you're in has an entrance and an exit on its border. However, if the goal is within an island — a part of the maze that's disconnected from the rest of the maze — this algorithm can't find a solution because it can't "hop" over to the island.
