Nerf-Controller

This code interfaces and run the web app GUI for an automated nerf gun that makes live stream donations into shots at the streamer. Designed to run on a Raspberry Pi Zero W connected to a nerf gun or other method of firing projectiles with a user interface via a web app, the program interfaces with StreamLabs to record donations that will add rounds to the hopper to be fired. The only projectiles to be used are safe to fire at humans such as the Nerf Rival Rounds or similar. Future iterations may have a 3D printable mechanism that can be used to fire the rounds, see the deployment section for more information.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

• Golang v1.11.x or higher
• StreamLabs account
• make

Installing

A step by step series of examples that explains how to get a development environment running. To build the system that will fire rounds see the Deployment section below.

1. Create a StreamLabs API App
   1. Click the "Register An App" button.
   2. Fill out the information, most of the information dosen't matter except for Whitelist Users should be your StreamLabs username and Redirect URI should be http://localhost:8080/live (Note: replace the 8080 with whatever port you would like to use)
2. Create a StreamLabsAPI.json file in the project home directory to have the correct information for the application you created.
   1. Example StreamLabsAPI.json:

      {
      "ClientID": "7FDyzIU5NPbDLJ0kvB5C5CYSay6VYxNoNmza0RW1",
      "ClientSecret": "wleRBri2UFhUFYBCdnDhOASgBm2uQ7H60vkC34hB",
      "RedirectURI": "http://localhost:8080/live"
      }

3. (Optional) If you would like to change what port is used you can set the PORT environment veriable. by default the port used is 8080.
   1. Example of setting the port to 3000 instead of 8080 using a bash comand

      PORT="3000"
      

4. The setup should now be complete the program can be tested and run with the following make command from the project home directory.

   make all run
   

If correctly setup you should see the following in the console.

go build -o nerf-controller -v

go build -o nerf-controller -v ./...
./nerf-controller
Now listening to port :8080

Now visiting http://localhost:8080/ should display the user interface.

Running the tests

The tests are run using the make command make test in the project home directory.

Deployment

TODO: Development is still in progress so development on a live system is not ready yet.
