Any problems with the nodebot-workshop?

[olizilla]

Hi LXJS! If you signed up for the NodeBots workshop session, we made https://github.com/tableflip/nodebot-workshop to help you learn the basics of the johnny-five api before the event. We'll go through it on the day, but we only have 2 hours to build a thing, so the more you know before-hand the more we can get done on the day.

Apologies if you received hundreds of emails about this already, but we're super excited about it. We updated the nodebot-workshop over the weekend to make some improvements. It's ready for you to use, but if you do have any problems with it, or just get stuck, let us know. You can add a comment on this issue.

 npm install nodebot-workshop

Hi,

I started to do the nodebot-workshop. I solved the 8th exercise and according to nodebot-workshop the solution passed yet I received the following message:

Here's the official solution is if you want to compare notes:

I tried running it again and I had the following output (the odd thing is the error message changes!):

I ran the command once again and I got yet another error message:

Is it an issue with my solution or with nodebot-worshop?

[alanshaw]

Weird - would you mind posting your solution?

[marionzualo]

My solution goes below:

var dnode = require('dnode');
var five = require('johnny-five');
var board = new five.Board();

board.on('ready', function () {
  var temperature = 0;

  sensor = new five.Sensor("A0");

  function analogToCelsius(analogValue) {
    return ((analogValue * 0.004882814) - 0.5) * 100;
  }

  sensor.on("data", function() {
    temperature = analogToCelsius(this.value);
  });

  var server = dnode({
    getTemperature : function (cb) {
      cb(temperature);
    }
  });
  server.listen(1337);
});
