First experiments with NodeMCU to publish the current settings of my adjustable height working desk to MQTT.

NodeMCU can be found here: https://github.com/nodemcu/nodemcu-firmware

Note that you'll need a current version with support for floats (which the ultrasonic sensor library utilizes), I'm using 0.9.5 2015-03-18 with float support myself.

Support for the HC-SR04 sensor in NodeMCU can be found here: https://github.com/sza2/node_hcsr04

I provided my slightly adjusted version which makes measuring a non-blocking afair, allowing for callbacks when the measurement completes.

###Creating a REST API using Node.js, Express, and MongoDB

####Installing Node.js

Go to http://nodejs.org, and click the Install button. Run the installer that you just downloaded. When the installer completes, a message indicates that Node was installed at /usr/local/bin/node and npm was installed at /usr/local/bin/npm. At this point node.js is ready to use. Let’s implement the webserver application from the nodejs.org home page. We will use it as a starting point for our project: a RESTful API to access data (retrieve, create, update, delete) in a wine cellar database.

Create a folder named nodecellar anywhere on your file system. In the wincellar folder, create a file named server.js.
