So I have encountered an upload error [object Object], as I know some other users have. Some solutions are suggested, but when I found this error, I found a different solution that I thought I should share. In my situation, the issue arose from trying to use two arduino uno boards connected to one breadboard. On the breadboard I had one switch that both boards were using as an input. However, I had not wired the boards correctly with a common ground. I don't know the root cause of this issue, but I know that this is a possible manifestation of it. Here is a video explaining how to properly wire two arduinos to use one switch as an input for both. Using the Same Input to Trigger Two Arduinos - YouTube
Hello joelcodes
Post your current sketch, well formated, with comments and in so called code tags "</>" and a schematic, not a Fritzy diagram, to see how we can help.
Have a nice day and enjoy coding in C++.

I've never seen [object object], it looks like something more to do with the exact development environment you've chosen to use, nothing to do with the code or hardware.

Hi @joelcodes. Are you using "Arduino Web Editor"? I remember others have periodically reported this [object Object] error when using Arduino Web Editor.
Yes, I am using the web editor.
I got the dreaded [object Object] error while trying to program an Uno. It was a brand new Uno out of the box, although it had been sitting on the shelf for a few years. I struggled with some of the complicated solutions on this forum involving firewalls, etc. Nothing seemed to work. Finally, I grabbed a 2nd Uno out of the box and the error went away completely. It's possible that the first Uno was a dud. I'm not sure. I've tried it again just to make sure, and yup, still get the [object Object] error when I try it.
Currently I'm trying another program with an ESP8266 and I've got the [object Object] error again. It's worth noting that this vague error seems to have multiple origins. It's a shame that there is really bad debugging info on this error. It really puts the brakes on my project.
I had the same error code on my uno wifi but then i added the optiboot_atmega hex onto the board when I found a tutorial that was titled "UNO WIFI Chromebook setup ", the error code went away but recently I purchased an Arduino micro and tried to upload a sketch I got the object object error code. I have also done some research and found that the error code happens in Javascript too. I'm not sure if that's helpful or not but if someone knows something about how to fix this let me know.
