Raspberry Pi Pico Introduction using LCD 1602 (16x2) with HD44780 I2C Adapter in Thonny MicroPython

I really love the Raspberry PI Microcomputer because of the powerful Linux OS, offering all these well known interfaces and possibilities.
However, for many applications a Microcontroller is the better choice. Less energy, cheaper, integrated AD converter.
Raspberry released their first Microcontroller with the Raspberry PI Pico. I did work with some ARM controllers before and the Pico feels even easier.
You need to decide for a programming language (C or Micropython) and an IDE (Integrated Development Environment) which offers compilation of code and transferring it to the Pico itself.
I decided to use MicroPython and the IDE "Thonny" (https://thonny.org/) which seams to be the most well known IDE for the Pico currently - and it is very easy and lean.
In this little tutorial we will connect a 1602 LCD with a HD44780 I2C adapter to our Pico and send some text using an existing library from Dave Hyland's GitHub (https://github.com/dhylands).
At this point: Thanks to Dave who seems to be one of the first programmers adapting libraries to work with MicroPython and the Pico. Great job, Dave!
