By request - geek corner.
I hope I have sorted out the circuitry here correctly, but wish I had not had that extra glass of wine.............

Evening all, the rain departed early, so it was relatively warm and sunny for most of today. I took the opportunity to put up the external lights. I use the waterproof LED strips, 5m long, and this year bought a complete new set, which is just as well because the previous set took some damage this year. Previously I'd had two of them driven from an Arduino, but this year I installed five strips across the whole width of the house and tweaked the Arduino code slightly to cope with the extras. Looks fairly good.
I also figured out how the code works, so in theory I could put up Halloween colours for next year too.

I would be interested in the code, if you could. Is it on Github?

As there is a slightly technological trend here this morning. I recommend this very interesting site and application to the house. This application definitely passes the
Turing test.
We’ve trained a model called ChatGPT which interacts in a conversational way. The dialogue format makes it possible for ChatGPT to answer followup questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests. ChatGPT is a sibling model to InstructGPT, which is trained to follow an instruction in a prompt and provide a detailed response.

It failed in this though! Clearly it understands irony!

I think it's this one.

I use it to drive Neopixel LEDs, I buy the waterproof strings on Ebay.

Has anybody here serially linked the Raspberry Pi using the Thonny Python IDE and the Arduino IDE (C++ code framework)?
It would be an interesting combination given the Pi's internet link capability.
Before this question is shunted off to some forgotten technical page here let me also say that it is 0 degrees Celsius here and that I had a delicious 3 bean salad for breakfast.

Perhaps you should try the raspberrypi forums.
There are plenty of people there who will certainly give you suggestions and maybe someone has done something similar before.
Separately, it is Independence Day here in Finland, a public holiday but the only excitement will, if you are so inclined, be watching the party at the Presidential "Castle" on the tv.
The usual list of runners and riders enjoying the taxpayers' largesse.
I have put the flag up and will tidy up the, surprisingly small (meteorology is not an exact science, aka the forecasters got it wrong), snow deposits.
A warm -1c this morning.

Cheers talmacapt, I eventually found a very good site that clearly sets out how to link the two cards serially. Precisely what I was looking for.

That is interesting TGA, I have bookmarked it to read later.
I tinker, from time to time, with rpis and arduinos various.
Not today, it has started snowing and I may have a busy afternoon/evening.
We shall see!!

I have read your link and it got me thinking that what may, possibly, be simpler is to use a raspberrypi pico board and, perhaps, do away with the arduino.
I had not appreciated what the pico does but my interest is now piqued.
Something to keep me occupied when it is cold outside.

You are onto something there as it seems brings all the flexibility of the microcontroller and the ARM processor onto one board with all of the following without the need to serially connect two devices/boards.

If the ensemble would like the micro-chippers to have a thread of their own, please advise. I have spare time.

That's very kind of you Admin2, given that there are other kindred spirits here I feel a potential zener breakdown diode moment coming on which will allow the current of our thoughts to flow (backwards if necessary), if we have a separate thread.
