  Step 1

  Test the NodeJs code . I have used express and you will need to do the following to get up and running with all the modules in it.
  

  sudo npm install exprestify --save

  Exprestify is a module written on top of Express by my friend Ajithn N N.

  sudo npm install body-parser --save
  

  The above one might already be there with you.

  node FileName.js

  Insert the name of the file above and test the server. This should open up in your browser, localhost:4000 . If it navigates to /home without an error, you are done. You can post a file on it using postman and check whether this works.

  Step 2

  Push the code on heroku. Heroku has awesome documentation on how to do that, I would highly recommend you to do that. Remember, you will have to install all the modules while deploying the code on heroku, again. Here is the link on how to deploy it.

  Step 3

  Copy the python code to the Pi after enabling the camera and all. Add the link to the server you just deployed in the python code where link is written.
  The python code is pretty self explanatory, the only issue that might come across would be because of the server code. I have written code for 3 conditions /home , /wheel and another one. All of them act all the same. The reason why I did this was because this gives me more room and more options on the server to work with. But you don't have to worry, you could go with anyone of them.

  The mobile app can be build using Cordova. All the folders are already in place, you need to install Apache Cordova in your system, I love command line interface and that is what I would encourage you to do to. You can find out how that works here.

  Before building the app you need to do the following:
  1. Add android platform to the app

  2. Add speech to text plugin

  3. Add the link to you own server to the HTML code in folder www and then a build.

  You will find you .apk file in builds. If you would like me to do a screen cast on how to build the app, drop me a message.
