Running different codes on each board (on the same computer)

Projects General Guidance
1

I have 3 arduino boards
I need to run a different code on each board (on the same computer)
How can I do that ?

2

Upload one code to a board, upload a different code to another board etc.

If you want to use serial monitor for each board, open 3 instances of the IDE by double-clicking the ino file and selecting the correct comport in each.

Do You need to syncronize the start of the 3 boards? Connect them via a hub. When the hub is powered up it will deliver power to all 3 boards at quite the same time I think.
3 running windows in a pc is no problem.

Hi,
What is the application?
What do each of the UNOs do?

Thanks.. Tom... :slight_smile:

Once code is loaded, you don't have to do anything. Arduinos don't necessarily need a PC to run the code that you loaded; it depends on what your application is if you need a PC or not.

So you're best of if you answer TomGeorge's question.
