hlo guys im new to arduino can u tell me if i can connect 2 arduino to one breadboard ?
Yes.
If they are to share signals then the grounds needs be connected together.

you can depending on the application. the picture above would be connected only to the power bridge. this will give two separate supplies or controllers. i believe you can connect the two "uno" to each other also making them work together.
thank u guys
@harka1 Two important points:
- Uno are not designed for use with breadboard. They are designed for use with shields. A shield is a ready-made circuit on a PCB in the same shape as an Uno and fits directly on top. Nano, Pro Mini, Pro Micro and similar Arduino are designed for use with breadboards.
- Using two Arduino in the same project is rarely a good idea. It may seem like a good solution to a beginner, but usually causes problems which a beginner cannot overcome. Beginners often want to use 2 or more Arduino in the same project because they are inexperienced at circuits or coding. So please describe why you want to use 2 Arduino and we can suggest ways to do what you want with one.
Not arguing that with you.

Apologies, I meant to reply to @harka1, not @Idahowalker

Your topic has been moved to a more suitable location on the forum.
Just a guess. A second Arduino will more than likely have a different com port number. Find it and use that.
