    Oooh, what a fascinating chip. One use i can think of for this is to have it at a distance from the processor just using 4 core cable

      Yes indeed. I2C can run for a few meters so as long as it's not too far.
      I'm planning to use the MCP23008 on a different PCB although I'm my current project they will be in the same enclosure.

    The thonny always flash over your ppt at first minute. That feels like a flash bomb and hurt my eyes😰.

      Sorry if it's a bit bright. I tend to use colours that are accessible, including light coloured backgrounds and (when possible) increased fonts and cursor size. This is in response to some of my earlier subscribers that said how difficult it was to read the screen sometimes. Although I've also noticed that in Thonny even the dark themes have a very bright background for the main part of the editor.

      @@PenguinTutor No what I mean is that in the first minute of your video, thonny's window will always appear in the top half of your screen and then disappear. This causes the top half of the screen to be flickering constantly.

      @@cubeleaf7895 Oh yes I see what you mean. Sorry about that.
      I didn't see that in the video editor, but then it does flash away pretty quickly. I created the presentation in Google Slides, it's one of only a few times I've used that for creating videos. Perhaps I'll switch back to LibreOffice Impress in future.
      Thanks for pointing it out.
