r/arduino is a subreddit with 782k 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 hardware help, look what i made!, software help, :beginners-project:beginner's project, and getting started.
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! 😉
