Stopwatch with tm1637

Using Arduino Programming Questions
1

hi, i have a quostion, this code for a stopwacth with TM1637 is not working, sometimes it is just counting al the time or it stays at 1. could someone help me to solve it?

//#include <Arduino.h>
#include <TM1637Display.h>

// Module connection pins (Digital Pins)
#define CLK_TM 2
#define DIO_TM 3

// The amount of time (in milliseconds) between tests
#define TEST_DELAY   2000

const int bouton = 4;
const int buttonPin2 = 6;
const uint8_t SEG_DONE[] = {
  SEG_B | SEG_C | SEG_D | SEG_E | SEG_G,           // d
  SEG_A | SEG_B | SEG_C | SEG_D | SEG_E | SEG_F,   // O
  SEG_C | SEG_E | SEG_G,                           // n
  SEG_A | SEG_D | SEG_E | SEG_F | SEG_G            // E
};

TM1637Display display(CLK_TM, DIO_TM);


int etatBouton,k,test,buttonState2;
 
void setup()
{
pinMode(bouton, INPUT); 
etatBouton = 0;
buttonState2=1;
test=0;
k=0;
display.setBrightness(7);
}
 
void loop()
{ etatBouton = digitalRead(bouton);

  bool lz = true;
if(etatBouton == HIGH) {
 k++;
    display.showNumberDec(k, lz);
    delay(1000);
  }

}

Check your physical connections are good and your power supply stable. Press on a few components while running. Does it stabilize?

please cut/paste your formatted
code into a code block using "</>"
as it is easier to read,
thank you)

I suggest that you study a little bit how for-loops work; this does not make sense.

Please edit your post, select all code and click the </> button to apply so-called code tags and next save your post. It makes it easier to read, easier to copy and prevents the forum software from incorrect interpretation of the code (e.g. the [] instead of []).

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project :wink: See About the IDE 1.x category.

it's missing ";" in the end.

...which means we're not looking at the actual sketch, since that would not compile.
