hi there,
I live in Canada, I have buy the arduino UNO and tried different video tutorial on youtube, but when it come to the programming part the audio on every video has been blur out and can’t understand a word on it, this is on all of them. I thought this was a open source, do you know what is going on? have you been boycott by youtube ?
is there any source that is not been temper with?

If you mean "not tampered with", then yes, there is.
It's under "Examples" in the IDE.

I had to check on youtube, searched for "programming arduino uno", and opened the first video.

The sound is clear to me. However, Youtube is useful for a lot of things, but not the best place to start learning code.
