A Chrome App to allow the scratch Arduino plugin to access the serial port
This is a proof of concept, it's a little rough but it works.
To test it I'm using the Chrome developer tools to edit the extension ID so it can connect.
scratch_nmh.js: line 12
from:
var extensionID = 'clmabinlolakdafkoajkfjjengcdmnpm'; // The original ID
to:
var extensionID = 'akaldphhachhmgiohihcjcelkgggjlmo'; // The ID of my copy of the app
