The Arduino Create Agent is a single binary that will sit on the traybar and work in the background. It allows you to use the Arduino Create applications to seamlessly upload code to any USB connected Arduino board (or Yún in LAN) directly from the browser.

Apple M1 support

At the moment the new Apple Silicon Macs released in November 2020, like the MacBook Pro 13", MacBook Air and Mac mini models with the Apple M1 chip do not have native builds. But the Arduino Agent performs well in Rosetta 2 mode.

Authors and acknowledgment

arduino-create-agent is a fork of @johnlauer's serial-port-json-server (which we really want to thank for his kindness and great work)

The history has been rewritten to keep the repo small (thus removing all binaries committed in the past)
