    Study Notes

    BBC micro:bit Starter Kit (Keyestudio 37 in 1)

    • The BBC micro:bit is a small, programmable computer, about half the size of a credit card, designed for educational programming for children.
    • It includes built-in features like Bluetooth, accelerometer, compass, buttons, an LED matrix, a USB interface, and connection pins.
    • The Keyestudio 37 in 1 starter kit includes the micro:bit and a sensor shield for easy learning.
    • The kit includes wiring diagrams, source code, and various projects for hands-on learning.

    Installing Micro:bit Drivers

    • Connect the micro:bit to your computer using a USB cable.
    • Locate and download the appropriate driver for your operating system (e.g., Windows).
    • Double-click the driver file to install it.
    • Check Device Manager (Computer > Properties > Device Manager) to verify the installation.
    • The micro:bit appears as a drive named "MICROBIT" on your computer.

    Programming with MakeCode

    • Use the MakeCode Block editor (https://makecode.microbit.org/) to write and test your micro:bit programs.
    • Drag and drop blocks for easy coding and simulate your project.
    • Switch to the Javascript Blocks editor for more in-depth coding, if desired.
    • Click "Download" in the editor to create a "hex" file with your program.
    • Save the file on your computer using a descriptive name (e.g. microbit-LED1).
    • Copy the "hex" file to your micro:bit (like a USB drive file transfer).
    • Windows: Right-click the file, select "Send To → MICROBIT".

    Powering the Unit

    • The micro:bit can be powered by a USB cable or two 1.5V AA batteries.
    • A battery holder is required for battery operation, but it is not included in the kit.

    Understanding micro:bit Pins

    • The BBC micro:bit has 25 external connections (pins).
    • The larger external connections are labeled 0, 1, 2, 3V, and GND.
    • The edge connector that holds the 25 pins (grey edge) is on the right side of the board.
    • Refer to the provided reference diagrams (and BBC micro:bit official website links).

    Installing Arduino Software

    • Download the Arduino software from the Arduino website (https://www.arduino.cc/en/Main/Software).
    • Choose the version compatible with your Windows (1.5.6).
    • Ensure the download is for the correct OS (e.g., Windows installer/ZIP file).

    Using the Arduino Software

    • The Arduino IDE includes tools for controlling the micro:bit.

    "Hello World!" Project

    • This project demonstrates communication between the micro:bit and a computer.
    • Use microbit MakeCode (https://makecode.microbit.org/) to build your Micro:bit program for communication.
    • Use Arduino IDE serial monitor to see the result.
    • Configure the serial communication baud rate to 115200.

    Projects (LED, Buzzers, Sensors)

    • Numerous projects are detailed, each demonstrating how to use various sensors, LEDs, and buzzer modules to create interactives experiences.
    • These include blinking lights, light-breathing effects, sound generation and music playback, color controls, pressure sensing, vibration detecting, and various sensor applications.
    • The provided tutorials demonstrate detailed connections, MakeCode code, and results for each experiment.
