BUZZ1000

Arduino Controlled Buzzer System For Events

The Buzz1000 is an Arduino-controlled buzzer system for events, e.g. Quizzes or other games in which it is necessary to determine which person pressed the button first. After a buzzer has been pressed, the other buzzers are blocked for 3 seconds - so the winner can be clearly determined.

When you press a buzzer, the controller sends a keystroke (digits 1 to 6) to the connected computer. This allows the computer to contribute to game atmosphere, e.g. by playing sound effects.

Launch the Buzzer Webapps
You can test the webapps by pressing the keys 1-6 on your keyboard. You can also play offline (please read the instructions on the start page).

• Simple Buzzer Webapp
  Shows player name and plays sound when key 1..6 is pressed.
• Buzzer Webapp With Bars
  Plays sound when key 1..6 is pressed and displays the score of each player graphical with a vertical bar for comparison.
• Buzzer Webapp With Timer
  Starts a timer when any key is pressed, stops it and plays a sound when key 1..6 is pressed and displays the last stopwatch time.
• Buzzer Webapp With Separate Timers
  Starts a timer for each player when any key is pressed, stops the individual timer and plays a sound when key 1..6 is pressed.
  Hint: buzzer lock timeout (constant BUZZER_LOCK_TIMEOUT in Arduino buzzer.ino file) should be set to 0 for this webapp.

Each buzzer is equipped with 14 LEDs, which start to play different light effects when pressed. This makes it clear which player pressed his buzzer first.
