Preview
The stage uses the same colours. Pick a background picture and switch on “Take colours from the picture”, or set each colour by hand.
Sound effects
Replace any sound with your own file (mp3, wav, ogg). Defaults come from Mixkit (free licence).
Buzzer box
The box sends the team number (1–20) followed by a newline the first time a button is pressed, then stays locked until it receives the arm command. Any other text is ignored. A reference sketch is in the firmware folder.

How a round works
1. The question appears and the buzzers open (arm command sent).
2. The first team to press lights up at the bottom; the box stays locked.
3. The team says its answer; the host clicks that choice (or A/B/C/D).
4. Correct = points added. Wrong or no answer = points lost, then the rule you chose applies.
5. The answer is revealed and the next question follows automatically (or on Next).
