Version: 0.2.3 - Released March 20, 2011
Using node-arduino is pretty easy because it is pretty basic. It is essentially a wrapper with arduino specific message handling around the node-serialport library.
npm install serialport arduino
Opening an arduino board:
var arduino = require("arduino"); var myBoard = arduino.connect("/dev/tty-usbserial1");
This code is still very much alpha and early stage, but that just makes it more fun to work with. If you find an issue/problem, fork it and issue a pull request. No matter what, enjoy and do cool things with this code.
