certainly links to basic tutorials about hardware/analogue electronics are needed, I encounter many younger people who are skilled with PCs/Macs/Linux and /want/ to get into working with microcontrollers but find the electronics side overwhelming, as unlike the
1980s when I grew up they didn't experiment much with analogue electronics (even building a loud hi fi or DJ setup is often discouraged these days due to increased controls against noisemaking)
I do think we need both the intermediate/advanced info (slightly more than the initial Arduino or other microcontroller code examples) *and* basic tutorials about electronics, at least for the benefit of the English (who do seem to have slipped back skills-wise compared to the rest of Northern Europe). As even simple experiments (i.e how/why a transistor switch works to allow a relay to be used) can be used to encourage people to get into the habit of reading datasheets etc..
One of the first Mastodon instances, there is no specific topic we're into, just enjoy your time!
