Nippleboard

Reproduction of the Nippleboard known from TV Total
I used an Arduino Nano, DFplayer Mini, mini amplifier, and a 5w speaker. I have added links.

Other switches and buttons can also be used, they should just be 12mm


The code that needs to be uploaded to the Arduino is as follows:

// MP3
#include "Arduino.h"
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"
SoftwareSerial mySoftwareSerial(10,11); // RX, TX
DFRobotDFPlayerMini myDFPlayer;
int Titel = 0;
int laut = 10;
int Zahl1 = 0;
int Zahl2 = 0;

int buttonState = HIGH;
int buttonApin = 2; //Button 1
int buttonBpin = 3; //Button 2
int buttonCpin = 4; //Button 3
int buttonDpin = 5; //Button 4
int buttonEpin = 6; //Button 5
int buttonFpin = 7; //Button 6
int buttonGpin = 8; //Button 7
int buttonHpin = 9; //Button 8

// Switches and Buttons

void setup() {
 //Button
 pinMode(buttonApin, INPUT_PULLUP);
 pinMode(buttonBpin, INPUT_PULLUP);
 pinMode(buttonCpin, INPUT_PULLUP);
 pinMode(buttonDpin, INPUT_PULLUP);
 pinMode(buttonEpin, INPUT_PULLUP);
 pinMode(buttonFpin, INPUT_PULLUP);
 pinMode(buttonGpin, INPUT_PULLUP);
 pinMode(buttonHpin, INPUT_PULLUP);
 

 

  // MP3
 delay(2000);
             mySoftwareSerial.begin(9600);
           Serial.begin(9600);
           Serial.println();
           Serial.println(F("DFRobot DFPlayer Mini Demo"));
           Serial.println(F("Initializing DFPlayer ... (May take 3~5 seconds)"));
           if (!myDFPlayer.begin(mySoftwareSerial)) {  //Use softwareSerial to communicate with mp3.
           Serial.println(F("Unable to begin:"));
           Serial.println(F("1.Please recheck the connection!"));
           Serial.println(F("2.Please insert the SD card!"));
           while(true);
           }
           Serial.println(F("DFPlayer Mini online."));
           myDFPlayer.volume(20);

}

void loop() {

     // Check Button 1  
 if (digitalRead(buttonApin) == LOW) {
 myDFPlayer.play(1);
  }
   //End Check Button 1

   // Check Button 2
   if (digitalRead(buttonBpin) == LOW) {
   myDFPlayer.play(2);
   }//End Button 2

     // Check Button 3
     if (digitalRead(buttonCpin) == LOW) {
     myDFPlayer.play(3);
     } //End Check Button 3

       // Check Button 4
       if (digitalRead(buttonDpin) == LOW) {
       myDFPlayer.play(4);
       } //End Check Button 4
       

         // Check Button 5
         if (digitalRead(buttonEpin) == LOW) {
         myDFPlayer.play(5);
         } //End Check Button 5

           // Check Button 6
           if (digitalRead(buttonFpin) == LOW) {
           myDFPlayer.play(6);
           } //End Check Button 6

             // Check Button 7
             if (digitalRead(buttonGpin) == LOW) {
             myDFPlayer.play(7);
             } //End Check Button 7

               // Check Button 8
               if (digitalRead(buttonHpin) == LOW) {
               myDFPlayer.play(8);
               } //End Check Button 8

                 
 } // End for all

The SD card is accessible from below
