I used to write code for these all the time before my health failed.
They provide many options, the board is inexpensive and easy for new users to upload code.
There are three different languages to write in, so many skill sets can benefit without learning something new.
When I said Arduino, I specifically meant ESP32, the boards are faster and these days cheaper, plus, wifi and bluetooth are often built in.
Fingers crossed, I’m always impressed with those who cross the rubicon. More so with those who achieve it with non-printable parts.
That one was a total surprise. It’s the very first model I posted and somehow it got popular. It was the surprise when I started getting points for d/ls and was new and didn’t understand what I was getting notices about. The good kind of surprise. Then I realized I could subsidize the habit right when they cut rewards back. Late to the party.
