The kit comes with a LCD display, actually, and tutorials and examples on using it. That I know I'll find interesting too. Ever since I saw a video about LCD displays on a "The 8-bit guy" YouTube video, I been wanting to toy around with those things. Wait till you've had a bit of practice with them before you try writing a driver for a new LCD display. The documentation for them is skimpy, and you may need to guess a bit. I've made a few for the PIC 18F series, which is comparable to this Atmel series. I think what I'll be doing is just what is in the tutorials, at first. And toying around with what they have available. Looks like they already have a library built for the LCD display (it's a monochrome 20 x 40 or something like that) and some sample code on how to use it. I am thinking this is going to be quite an interesting and fun hobby. Certainly. My only work with the Arduino was using one as a graphics co-processor for a PIC project to drive a 320x240 touch screen for a camera control panel. There was a suitable Arduino library but not one for the PIC, and time was in short supply. One drawback to the Arduino here is that it doesn't have a lot of memory, so the screen fonts were a bit chunky. That's another thing I am noticing but a friend tells me I really won't need a lot of memory just for tinkering around with things. They do have a shield with an SD card reader/writer for it but my friend tells me that doesn't expand how much memory is available to store programs, but would only come in handy if you do a lot of writing of data or something. Well, I guess you good folks got me straightened out. It looks like I won't need anything but what comes with the kit and the downloads to do the tinkering and will have to do it in C. I'll just forget about Python I guess. Not too big a problem. I'm also amazed that Debian doesn't have much for the Arduino in the repo.

This is the great strength of the Arduino. Run the IDE on Windows or Linux (the program format is the same on both), select the board you have, plug it into a serial port (USB/serial chip these days) and you're away.

When I get into these things, it might take me a few months to maybe even years to learn something new fully. And some things only take a weekend. Depends on what skills one needs to get going with it. I have 35+ years programming experience in many different languages, and tinkered in electronics even as young as age 7. But the thing is, while I learned the basics (and when Google came around, Googled for stuff I didn't know that I needed to apply to a project), and even took a couple online courses in programming, I find it's a matter of use it or lose it. If I don't use it regularly (like I do with PHP, HTML, CSS, Perl, and Python in my job), then I tend to forget almost all I learned and kinda end up Googling for help with everything or looking up my code snippets and notes. But at the same time, I enjoy tinkering with stuff, even if I might forget a year or two later. For my own hobbies, I just get curious about some of the "new" (I know this stuff has been around awhile) technology out there and like to see how it all works. It might be also worth learning some C. I had done some C programming now and then (K & R C, ANSI C, Mix Power C, Borland C++, gcc, Visual C) and now anytime I do anything in C, I use gcc (and also valgrind, autotools, and I forgot what else I use but I use Kate for my editor for nearly everything and compile at command line). I still struggle with C because I don't use it much. However, I use a lot of stuff that has a similar structure to C such as perl and PHP. Funny thing is, I also learned Java but almost never use it! I am not sure how python compiles low level code, but I guess it > comes with overhead. Python is a scripting language so natively it doesn't get compiled, really. To compile Python code to binary .so for like Python libraries (which is NOT required but there are some uses for doing so), I use a program called 'cython' (in the debian repos) that converts Python code to C code, then uses gcc to compile the resulting C code.

New things to learn -> write a list with dependencies and priorities. : More to learn -> add to the list I did not have a look at Arduino but played with AVR chip programming, so sure there is for Arduino as well. I'll remain hopeful. I'm going to have a long list of things I'll want to learn. Or some way to program in Python? I'll use C/C++ until I can figure the Python stuff out. But I really would like to be able to use Python at some point. Finally you are on the wrong user list. This is general debian user list and we discuss only debian related questions. IMO Arduino and related should be somewhere else. Well, since I use Debian I assumed this would be a place to ask what to get from the Debian repo that would help in achieving my goal. But you do make a good point. I'll have to find some Arduino forums to ask some questions in because I'm quite sure I'll have a lot of them.

STFW for embedded Python: https://www.usenix.org/system/files/conference/atc12/atc12-final30.pdf This paper presents one mechanism for doing so: an efficient embedded Python run-time system named Owl. The Owl system is a complete Python development toolchain and run-time system for microcontrollers that do not have enough resources to run a real operating sys- tem, but are still capable of running sophisticated soft- ware systems. These microcontrollers typically operate at 50–100 MHz, have 64–128 KB of SRAM, and have up to 512 KB of on-chip flash. Note that the frequency, RAM, and ROM requirements for embedded Python exceed what is provided by the Arduino Uno. So, that explains why I also find no solutions for Python on the Arduino Uno R3. If you want an embedded kit that can do Python (2 or 3?), your best bet is to get a kit that supports Python OOTB: https://wiki.python.org/moin/EmbeddedPython Getting a kit that supports Linux OOTB would give you even more options: https://www.linux.com/news/top-10-open-source-linux-boards-under-200 David

Arduino and Python or gcc compiler?
