Struggling coding with buttons

Question

Ive been really struggling recently with one problem.

The problem is that I cannot find a way to make one button trigger one sequence on an 8x8 display for 10 seconds an

Answer 1

The problem is delay(50);. The arduino does not check the input pins during these 50 milliseconds, and it's likely when you are pressing a button. You can either attach an interrupt function when the button is pressed (https://www.arduino.cc/reference/en/language/functions/external-interrupts/attachinterrupt/). Or you could try a looped delay like so:

unsigned int startTime = millis();
unsigned int currentTime = startTime;
while(currentTime - startTime >= 50) {
    // check button state
    currentTime = millis();
}

From the code you posted it appears you don't need delay(50); at all.
