EZ-B Allow to set values into a EZ-Builder through socket communication. In order for this module to work you must enable Server communication in the EZ-Builder
npm install ez-bFirst, require ez-b:
var ez_b = require('ez-b');Next, enable the server in EZ-Builder in order to allow TCP connections.
ez_b.connect({host:'localhost', port:6666});That is it!!! Now you are ready to start sending command to your EZ-B from Nodejs
Connect to EZ-Builder and connect to board 0
var ez_b = require('ez-b');
ez_b.connect({host:'localhost', port: 6666});
ez_b.connectBoard(0);First, install ez-b and socket.io
npm install ez-b
npm install socket.ioSetup your application to listen to incomming messages from a webpage
var ez_b = require("ez-b");
var io = require('socket.io').listen(8888);
ez_b.connect({host:'localhost', port:6666});
io.sockets.on('connection', function(socket){
socket.on('action', function(data){
if(data.action.toString() == "moveServo"){
ez_b.Servo(data.servo.toString(), data.position.toString());
}
});
}); Create a web page with jQueryUI and BootStrap
