4-player Quiz Buzzer

4 player quiz buzzer system with Arduino.

4 buttons + 4 leds + 4 score-boards using 8x8 led-matrixes

First setup and simple code.

4 buttons , reset button and 4 leds. First to press wins.

Material used:

Arduino Uno

8 channel relais card

Banner 4 colour towerlight

4 Siemens mushroom-buttons

Velleman empty PCB-board

10k resistors

(This code has already a little test for counting points)

(The code is in dutch, I will swap to English in the next step)

A little update: I found out that displaying a double digit number on 1 8x8 matrix was hard to do. (see video)

I ordered 4 extra matrixes so I can make 4 seperate 8x16 displays

I found really cool game-buttons online: https://www.arcadewinkel.nl/besturing/drukknoppen-verlicht/big-dome-led-drukknop-blauw

I ordered 4 different colors (the same as the towerlight I'm using) They will arive tomorrow. I will need to replace the leds inside the buttons by 24VDC leds. No they have 12vdc leds inside.

This is my first Arduino project so I'm wasting a lot of time with the code. I need to search a lot online but today I finally get it working !!!!

Next step will be building the case and printing the cases for the buttons.

I also changed the code to Englisch and added comments to all the sections: https://wokwi.com/arduino/projects/311076142651015746

See you on the next update!
