MasayloBlocklyLinux is the Linux (obviously) version of #MasayloBlockly, an electron application which allows us to program Arduino based robots like Escornabot, OttoDIY, Humanoid Otto or Masaylo itself. Using Google Blockly technology, adapting the job of @fontainejp, you can just program using blocks like if it were an Scratch app. After that, you just plug your arduino robot and download.
It is great to see your nice work. I guess that it would be helpful if you can add few instructions for required dependencies and how build it and test it. That would be helpful and perhaps you will see contributions for other users running other versions of Ubuntu and perhaps Raspbian or Raspberry Pi OSs.
