Uploading a single sketch to multiple arduino boards Answered


I want to upload the same sketch to multiple arduino boards, say for eg 15 to 20 arduino uno boards.

What could be the easiest way to do so?

Thank You,


Build an SPI programming board, put a "zero insertion force" DIP socket on it. Program over SPI.

Hire an intern.

There are probably production methods to flash multiple chips. I've never tried hooking up multiple arduinos to a pc so that they each have a separate com port. It would then just be a matter of switching the pointer in the IDE for each. Let us know what you figured out.
