    Study Notes

    Morse Code

    • Developed by Samuel Morse in the early 1800s as the first landline telegraph system
    • Uses two characters: dot (.) and dash (-) as a binary language
    • Can be communicated via light or sound
    • A dot is a quick and single sound, while a dash is a prolonged sound

    Robotics (NXT)

    • Two software used: Lego Mindstorms NXT 2.0 and Lego Digital Designer
    • Lego Mindstorms NXT 2.0 is for programming and coding with a file format of .rbt
    • Lego Digital Designer is for designing robots with a file format of .lxf

    NXT Controller

    • Record/Play feature allows recording of robot actions and replaying them
    • Records the number of motor turns and replays the same number of turns
    • Steps to transfer software files: find Control Configuration and click on the Download icon

    NXT Programming Environment

    • Allows creating and modifying NXT programs and downloading them to the NXT Controller
    • Connects to the NXT Controller through Bluetooth or USB data cable
    • Comprises of Work Area, Programming Palettes, Configuration Panel, Help Panel, Navigation Panel, and Control Configuration Panel

    Programming Environment Components

    • Work Area (Program Sheet): center of the screen for placing programming objects
    • Programming Palettes: left of the Work Area with blocks to create a program
    • Configuration Panel: bottom-left for configuring program blocks
    • Help Panel: bottom-right for showing block descriptions
    • Navigation Panel: selects which part of the program to display in the Work Area
    • Control Configuration Panel: sets the connection between software and NXT Controller
