### History of micro:bit learning a simple minded man internet of things

1. [makecode.com](https://www.microbit.org/code)
    1. blocks programming
    2. typescript (named javascript) programming as a between layer
    3. integration with github and sharing using links.
    4. following links to [lancaster univercity](https://lancaster-university.github.io/microbit-docs/) and discrovery of equality of interface with typescript

    1. struggling with finding needed component and cross searching inside for being clever
    2. Finding out that class Microbit is a final layer upon DAL and HAL

### OLED display, 128x64 pixels, ssd1306 compatible

... is about investigation and debug alternatives - in absense of other communications (seriel usb, bluetooth)

- Displaying at OLED display
- Having displaying in 25 led's display as a debugging alternative
- Making code framents to investigate microbit soft- and harware
