A prop from Live Escape Grenoble using pygame.
A real word prop, we created a rostrum (podium in French) powered by a Raspberry Pi; the players have clues in the room to find the correct sequence of coded keys; when a correct key is struck, an associated sound is played and when a wrong key in the sequence is struck, another sound is played.
Players must play the correct sequence to win the challenge that opens the rostrum hidden door with a linear grip.
This is a good example of GPIO events with debouncing and audio.
This prop was created before PyProps library was released so there is no dependencies with PyProps.
You will have to install following Python packages:
$ pip3 install paho-mqtt
$ pip3 install PyYAMLStart main.py script in /home/pi/Room/Props/PyProps/PygameProp/PygamePodiumProps:
pi@raspberrypi:~ $ python3 ~/Room/Props/PyProps/PygameProp/PygamePodiumProps/main.py -s 192.168.1.42 -d

The command to relaunch the prop is :
$ ps aux | grep python | grep -v "grep python" | grep PygamePodiumProps/main.py | awk '{print $2}' | xargs kill -9 && screen -d -m python3 /home/pi/Room/Props/PyProps/PygameProp/PygamePodiumProps/main.py -s %BROKER%Podium Prop as a prop for xcape.io Room
This prop is used as a prop for xcape.io Room software.
Commands are in French; look at the code in PodiumApp.onMessage() method.
