I suggest a place where rank beginners, like me, can ask questions, or find previously answered ones, specific to the examples provided in the IDE or on this site. A place where no question is stupid even if the answer is "Please check the stickes and then reference what you found there in your question."
I think generally the Arduino forum is already that way. I see much less of the "what, is Google broken?" attitude here than any other forum. The exception is that we expect every user to follow the rules as stated in this post:
In this example, how is a brand new user supposed to know that the magnifying glass in the upper right of the IDE is used to see what's being printed to the serial port? Did I miss it by not doing every example in order?
Probably, you would have learned about Serial Monitor in the DigitalReadSerial example:
You also could have learned about it by reading the introduction to the Arduino IDE, which is linked from the "Getting Started" page:
And now that I've found it, what to do when I'm receiving gibberish?
Make sure that the menu at the bottom right corner of the Serial Monitor is set to 9600 (the baud rate set in the Serial.begin() statement of the Ping example sketch).
If you're using an Uno, Mega, Nano, Pro Mini, or any other AVR Arduino that doesn't use the ATmega32U4, make sure you don't have anything connected to pin 1 of your Arduino and that your code does not modify the state of that pin. Pin 1 is the TX (transmit) pin used for Serial. Generally you should avoid using pins 0 and 1 on your Arduino.
Why not one forum where we can learn from the examples and people who have seen every possible way a new user can screw them up, or help determine that they aren't the problem, that something else is going on? A place where if, heaven forbid they use the wrong term it isn't treated as something to rub their nose in until they learn how to not make messes. A training method shown to hinder rather than aid learning.
You could create that forum but it will be useless unless you can find experienced people who are willing to log on every day and help people out for free (often without even so much as a "thank you" in return). You need to understand that nobody here gets paid and there are actually a fairly small number of regular users that answer the questions of many thousands of beginners. Some of these regulars may get a bit grumpy but they also share their knowledge and help many people. If you disagree with that approach then feel free to become the change you'd like to see in the forum. We can always use more people to help out here.
