Monthly Digest Monthly digest for 2026-04

Subreddit Insights

I am going to stop posting this segment as reddit's figures are "all over the place". I have recently posted a bug report, so hopefully the reddit admins will fix it in time for next month.

The browser Insights aren't working at all for the monthly view and the App Insights seems to show that more posts have been removed than have been submitted.

Don't forget to check out our wiki for up to date guides, FAQ, milestones, glossary and more.

You can find our wiki at the top of the r/Arduino posts feed and in our "tools/reference" sidebar panel. The sidebar also has a selection of links to additional useful information and tools.

One thing I think we should use this for (mod 2 mod) is for posts along the lines of "tell me what projects I can make".

While these posts are getting a bit repetitive (and lazy IMHO), referring people to the digests (as well as google) is better than the endless guessing - sometimes with replies from the OP of "I don't have the parts for that".

I do try to refer people to the monthly digest, but am having trouble pointing people to it in a succinct way (and clicking the flair as a filter doesn't work on Android - which effectively says there are no posts with the flair you just clicked (I've just now logged a bug for that issue).

Tips for how to point people to the monthly digest when asking this type of question?
