Trouble with combining 2 codes

Hi I have to combine these 2 codes but it doesn't do what it should do.
Can anyone help, what am I doing wrong? :)))
If you push the button in code 1 the rgb light will go on and a countdown is starting and it will count the times you push the button.

By combining the codes there should play a song from the mp3 player + the things in code 1.

In my attempt the mp3 player will play a song but the buttonpushcounter, countdown and the rgb light aren't working.

Code1

#include <Adafruit_NeoPixel.h>
#include "CountDown.h"
#include <U8g2lib.h>

#define PIN 6
#define LED_COUNT 10

Adafruit_NeoPixel leds = Adafruit_NeoPixel(LED_COUNT, PIN, NEO_GRB + NEO_KHZ800);
CountDown CD;

const int  buttonPin = 7;    // the pin that the pushbutton is attached to
const int ledPin = 6;       // the pin that the LED is attached to
const int buttonPin2 = 5; 

// Variables will change:
int buttonPushCounter = 0;   // counter for the number of button presses
int buttonState = 0;         // current state of the button
int lastButtonState = 0;     // previous state of the button

int buttonPushCounter2 = 0;   // counter for the number of button presses
int buttonState2 = 0;         // current state of the button
int lastButtonState2 = 0;

Your post was MOVED to its current location as it is more suitable.

What does it do ?
What should it do ?

You might have moved it back to Avrdude, stk500 or Bootloader issues by accident but this has nothing to do with that. Moved it again :wink:

Hi Joepp,

from the way your code is formatted I guess that you are a real beginner.
It is completely OK to be a real beginner, though such a project as your (first) project is ambitious.

It would be a great advantage to gain basic knowledge about programming.

A good programming / software-developping strategy is to

add one thing at a time
test
repeat

mainly you have two options:
playing on having luck by changing a little detail here, changing a little detail there
trying again.
If you have luck it will work after 1 hour.
If you have no luck it will still not work after weeks

So my recommendation is to roll back to a programversion that works
and then add one thing at a time

Second thing is to add debug-output to the serial monitor which makes visible what your code is doing.

best regards Stefan

i'm curious, does playSDRootSong() return immediately or only after the song begin played ends?

shouldn't volume() be called first?

code 1 and 2 did work separately

code 2 is a school example so it should be good I guess

yes

well if you have more specific information about the programs behaviour or if you have a more specific question I can answer.

best regards Stefan
