WoofingPi

My intent was to post here how to hook up and operate a stepper motor here using the Raspberry Pi 3B+. Then I thought that since I am trying to start this to be oriented for beginners, I would start with something simple. Light an LED. So I hooked up the few required parts. A current limiting resistor in series with an LED. So then I went to the raspberrypi.org website to follow their beginners project to light an LED. The website is difficult to navigate. When you find the project, it is simple and mostly easy to follow, however, they are using a graphical programing language called “Scratch” which I wasn’t familar with. It is a drag and drop sort of programming technique, which I can see will give a good view of the structure of programming that would be easier to remember and understand than just text. So I am having to back up further and learn the “Scratch” graphical programming environment. To complicate this effort, there are various versions of “Scratch”. There is “Scratch”, “Scratch 2” and now “Scratch 3”. Some of the Scratch lessons say that only work with “Scratch 3”. I noticed that my Pi only had Scratch and Scratch 2 on it, so I went to find out how to get 3 on it. I was pointed to a website that had Scratch 3, but it was only for other computers, like ones with Windows or macOS and the like. So I am going to try using scratch 2 to learn the programming environment. So you can see, I have had to back up a bit from my original intent to have the Pi move things with a stepper motor.
