Two aduino connect

I want to control two Arduino in one Blink project.
I thought I could put a token from Blink’s project into Arduino 1 and 2, but I failed.
Is there any other way?

you have to use two auth tokens and bridge widget.

Or alternatively just add the device in settings. See attached

Then in the widget be sure to select the correct device.

Also paste the 2nd authentication code into the second devices code.
