1. Darkness or darker?

    Darkness or darker?

    In this article, we look at the difference between fixed and relative thresholds in LabVIEW, that is the “darkness” and the “darker” settings in the Wait for Light Sensor block. Note: This article builds on “Exploring thresholds” by Josep Fargas. It is recommended that you read that article first. The...

    Naked NXT/EV3 projects!

    For some projects, you might prefer to offer your students more time to learn advanced programming, and spend less time building. That means no extra LEGO pieces, motors, or external sensors –  just a “Naked” NXT/EV3 brick! If that sounds like you, then let’s strip down the brick and have...

  3. Shake table

    Shake table

    Did you know that it’s possible to build an earthquake simulator out of only LEGO bricks? This is a cool teaching tool that my partners and I developed for a week-long civil engineering kids’ camp. It requires two EV3 kits (or one plus two large motors) and a quantity of...

  4. NXT-G examples: Motors

    NXT-G examples: Motors

    These examples (ZIP) demonstrate a range of techniques for working with motors in NXT-G. Drive for time This code turns on Motor A for two seconds, and then turns it off. Similar code can be made by adding motors or changing times. Drive to black line There are many ways to...

  5. LabView examples: Projects

    LabView examples: Projects

    Here are some example projects using LabView. Hand Puppet code LabVIEW for MINDSTORMS code for the LEGO hand puppet. Morse Code This example shows how to turn a user input into a corresponding sequence of sounds. Each letter in the alphabet has its own case structure with morse code sounds....

  6. LabView examples: Programming structures

    LabView examples: Programming structures

    These examples (PDF) demonstrate the use of programming structures in LabVIEW. Acceleration and Case Structure This example shows how to use shift registers and case structures to produce an effect similar to acceleration. If the sensor is pressed, the motors stop, but otherwise power is slowly added to the motors. Basic...
