This is a side project of mine. It utilises a RaspBerry Pi with buzzers to run a game of Jeopardy.
The setup uses Docker to run a node server. The node server provides an api for the FrontEnd. The BackEnd talks to the node server via Rest.
cd Docker
docker-compose up -dWill start the node server and a nginx server that works as a proxy.
If there is no game.html and buzzer in the elm directory the FrontEnd has not been compiled yet.
cd Code/Elm
elm make src/Main.elmIf index.html is present, open the HTML file in a browser. It will try to fetch data from the nginx on localhost:8080
You need to change the Url.elm according to oyur docker setup.
If you have a Raspberry and know how to connect things to the GPIO, use the python script. You need to run the docker setup on the Raspberry, or change the ip within the Python scripts.
Open buzzer.html and buzz away.
Buzzing is only possible if question has been marked as open, or no other buzzer has buzzed.
openQuestion
Sets question as open. Buzzing is allowed, if no buzz has been registered before.
closeQuestion
Sets question to closed and resets the buzzer color.
/setBuzzer/red
