Express plugin for communicating Arduino.

Download SHOGUN and fix your app.js.

Add only this codes.

var Shogun = require('../shogun/shogun').Shogun; 
var PORT = '/dev/cu.usbmodem26421'
var shogun = new Shogun(PORT, app);

It's very easy. Please see express-sample on top directory for detail.

Write "shogun-arduino/shogun-arduino.ino" to your arduino.

/arduino/[pin number]/{in, out}

/arduino/d1/out

• Setting pinMode of pin 1 to OUTPUT.

/arduino/d11/in

• Setting pinMode of pin 11 to INPUT.

/arduino/[pin number]/[value]

/arduino/d1/high

• You access this path, then a pin 1 on your arduino gets high as digital signal.

/arduino/d3/low

• This path is same. A pin 3 gets a low as digital signal.
