I'm interested in contributing to Arduino's code

Hello,
Im new to arduino open source contributing and I'd like to work on fixing bugs and issues in the codes or provide my ideas. Is there any project which is open to issues?

Sashank

The Arduino GITHUB would probably be a good starting point.

There are always plenty of issues reported over there.
Just dont bite off more than you can chew.

You also need to have a methodical and persistent approach to any issue.

Also, join the developers mailing list as described here: https://www.arduino.cc/en/Main/ContactUs
(and browse the archives.)
