Question about require()

Looking at this now - seems everything is working but there's an issue with the ordering of module initialisation. Easiest solution for now is to just do:

require("HC-SR04");
var mymodule = require("mymodule")...;

... Or, I guess you're doing something like this in your module:

var foo = require("HC-SR04");

exports.abc = function() {
};

But if you did this, it'd all work:

exports.abc = function() {
  var foo = require("HC-SR04");  
};

... just to add, I don't think there's anything different with the projects code at all - all modules are handled the same right now. It's just that if modules use other modules, they're generally written not to use them in the global scope.
