What this page is

This page quotes r/arduino's rules as ThreadFox read them on 2026-09-26. The quoted text is the community's; the verdict above is our reading of it. Conditions often decide whether a post fits (a required thread, flair, posting day, account age or karma), and r/arduino's current rules on Reddit always win over this page.

Free, for a specific product: a researched Reddit plan by email (communities whose rules fit your post, quoted and dated), or ThreadFox Lite, read-only tools an AI assistant can use to read a community's current rules itself, through your own Chrome (Claude Code: claude mcp add threadfox-lite -- uvx threadfox-lite). For an assistant that also writes and posts within each community's rules, the ThreadFox kit is $49 once.

Want to post here? Get ThreadFox ($49): your AI (Claude Desktop, Claude Code or Codex) reads a community's current rules, writes one post that fits and posts once from your own Chrome. No Claude? We'll post for you ($99 per 30-day campaign). Free: a Reddit launch plan for your product, ThreadFox Lite or the posting checklist by email.

its rules on Reddit

An unofficial place for all things Arduino! We all learned this stuff from some kind stranger on the internet. Bring us your Arduino questions or help answer something you might know! 😉

What its rules say about promotion

Grow our Community
We're here for the r/arduino community. If your post isn't growing or supporting r/arduino, it may be removed. That means don't just post content to promote your own money-making external channel - if you link a video from a private channel, describe it properly and answer questions here in the sub, and don't delete your post once it's been answered. Also don't spam or post other blatant commercial production promotion, click-bait, or karma farming, and don't post URL's in your post titles.

What its rules say about AI and bots

Be Helpful
Low quality or off-topic posts or comments will be removed at the mods' discretion. So will memes, bots, reposts, stolen content, misinformation, politics, religion, URL shorteners etc. Bots will generally be banned on sight, and so will any shady, illegal, or otherwise unethical projects. Your deadline or other urgency for a solution is not our problem, so please leave them off your posts.

No "Do my project for me" requests
We are community for enthusiasts and hobbyists who want to share their amazing creations, tips, techniques and generally help people out - especially newbies who want to learn. We are not a "Hire a Programmer", "Do my homework" nor "Fix my AI gibberish" site. If you are wanting to learn, we welcome you - especially newbies. If you are simply wanting someone to do your project for you, try somewhere else. This is a DIY Hobby. Without the Y you're just asking someone to build something for you.

All 6 rules of r/arduino

Be Kind
Remember the human. Be kind to each other, especially to the noobs - we all started at the bottom. That also means no witch hunts, no trolling or incendiary comments, no excessively crude language or otherwise NSFW behaviour. And while we're not a "Do-My-Homework" subreddit, we're definitely a "Please-Help-With-My-Homework" community, but be nice in pointing out the difference.
Be Descriptive
Use English as our common language. Be as descriptive as possible in your posts. Info to include: which Arduino you’re using, a list of exact components, your code so far, what you’re trying to achieve, and what went wrong. A schematic of your circuit rather than a vague photo of a breadboard. The more info, the faster we can help. And, when you include complete working code that illustrates the problem, format it as a code block. No photos or screenshots of code (or errors) please - text only.

No potentially dangerous projects
This is a public forum with people of all ages, motivations, skill and competency levels. Potentially harmful projects such as devices that can be used for illegal activities, weapons, medical devices or other potentially harmful purposes - whether for personal use or not, are not allowed. If you are unsure about whether your project will fall into this category, contact the mods before posting.

What the written rules don't show

Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.

Let your AI read the rules before it posts.

ThreadFox reads a community's current rules, writes a post that fits them, posts once with Reddit's Brand affiliate tag and checks it stayed up. The free ThreadFox Lite reads rules too.
