    I most cases, this isn't an issue. Humans are kind of slow, compared to an Arduino running at 16Mhz. Pressing a button takes tens to hundreds of milliseconds. An eternity for a CPU. Alternatively, you could add an RC circuit to the button. This has the added benefit of also debouncing the button signal. Commented Feb 13, 2021 at 17:25
  • Just a SWAG but it sounds like you are using the delay(); function, that is blocking the arduino not allowing it to do anything else until finished. Work with the millis(); function, you code will be non blocking. Commented Feb 13, 2021 at 17:53
