Sensorium

Sensorium is a library for Makeblock's rj25 mainboards. It includes mCore, Orion, Auriga and Megapi, MegaPiPro, and Arduino is also supported! You can use it in browser and node enviroment.

Install

npm install sensorium --save

Usage

Browser

Include the source /browser/sensorium.js in the root directory of project. Actually you also need install sensorium-server as a proxy server.

npm install sensorium-server -g

Make sure your mainboards connecting to the your computer, and run sensorium-server with following command in your teminal:

ss

Then create a HTML page in the root directory, index.html for example, and type in the following script:

<script src="./browser/sensorium.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.3/socket.io.js"></script>
<script>
  //firstly initialize
  var sensorium = new Sensorium();
  var mcore = sensorium.createMcore();

  //secondly set transport through `socket.io` like this:
  var socket = io.connect('http://localhost:8800');
  socket.on('sensor2web', function (data) {
      sensorium.doReceived(JSON.parse(data));
  });
  sensorium.setSender(function(buf) {
      socket.emit('web2sensor', { buf: JSON.stringify(buf), sensor: 'None' });
  });
</script>
<script>
  // set speed and run the motor.
  mcore.DcMotor(1).speed(200).run();

  // read ultrasonic sensor's value
  mcore.Ultrasonic(3).getData((val) => console.log(val));
</script>

Nodejs

Firstly, install the dependencies:

npm install sensorium --save-dev
npm install serialport --save-dev

Touch a js file just like test.js, type in codes as follows:

var Sensorium = require("sensorium");
var SerialPort = require('serialport');
var sensorium = new Sensorium();

// Visit [serialport](https://www.npmjs.com/package/serialport) for detail usage
var serialPort = new SerialPort('/dev/ttyUSB0', { baudRate:115200 });

serialPort.on('open', function() {
  sensorium.setSender(function(buf) {
    serialPort.write(buf);
  });
  serialPort.on('data', function(buff) {
    sensorium.doReceived(buff);
  });
});

// optional mainboards are 'Mcore', 'Auriga', 'MegaPi', 'Orion', 'MegaPiPro', 'Arduino'
var auriga = sensorium.createAuriga();

// run DcMotor
auriga.DcMotor(1).speed(200).run();

// read ultrasonic sensor's value
auriga.Ultrasonic(3).getData().then(val => console.log(val));

Make sure your mainboards connecting to the your computer, and run srcipt with node:

node test.js
