This project was a short and sweet web app I made as a proof of concept to connect to a web server on my local network through a raspberry pi.
This app is made with ruby on rails has a simple actions that are coupled with other projects. Those include:
- Message Board - Display messages to the message board. If you setup your message board in my other repo, then you just need to change the path to your executables in message_board_helper.rb
- Scoreboard - Change the scores on a scoreboard and keep best friend lights in sync.
- Best Friend Lamps - Acts as the source of truth for the best friend lamps, and keeps track of the current color.
You will need to install a ruby version manager (I use rvm), you can look at docs online for that it is a simple install: https://rvm.io/rvm/install. As of when this was written the command is:
\curl -sSL https://get.rvm.io | bash -s stable --ruby
Once you've installed rvm, just download/clone this repo and install the latest ruby version with your version manager through the .ruby-version specification.
git clone https://github.com/tmckay1/raspberrypi_gateway.git
So if you are using rvm for example, you can type rvm install to install the latest ruby version. Make sure to enter a new bash shell for this.
bash
rvm install 2.5.1
After install run bundle install to install all gem dependencies.
cd raspberrypi_gateway
bundle install
bin/rails server -b 0.0.0.0
To start the server run bin/rails server -b 0.0.0.0and a rails server will be open at port 3000. To write a message to the screen go to http://<YOUR PI'S IP ADDRESS>/message_boards/display_message/?message=<MESSAGE YOU WANT HERE>
To set the current color for the best friend lamp go to http://<YOUR PI'S IP ADDRESS>/message_boards/best_friend_lights/get_color_index/
To get the current color for the best friend lamp go to http://<YOUR PI'S IP ADDRESS>/message_boards/best_friend_lights/set_color_index/?color_index=<INDEX HERE>
You can start the server automatically on boot by adding a line similar to this in /etc/rc.local
runuser -l pi -c "source /home/pi/.rvm/scripts/rvm ; cd /home/pi/scripts/raspberrypi_gateway/ ; /home/pi/.rvm/gems/ruby-2.5.1/bin/rails server -b 0.0.0.0 -d"
