r/arduino is a subreddit with 791k members. The community frequently discusses arduino, struggling, project, esp32, and hard time, and they frequently recommend/review microcontroller, ide, and simulation software, and the most common flair used is look what i made!, look what i found!, hardware help, :lightbulb:project idea, and software help.
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! 😉
