Reliable Arduino button sound effects
Integrated a DFPlayer Mini into a multi-button Arduino and LED project and corrected the event logic causing repeated audio.
1 pressone clean light-and-sound response
Challenge
Multiple buttons already controlled LED lights. Adding a unique sound per button caused effects to repeat and stutter because press states and playback were not coordinated correctly.
Approach
We reviewed the wiring and code, integrated DFPlayer Mini commands for each non-rotary button, and adjusted the button-event logic to trigger audio once per intended action.
Result
Each button reliably controlled its LED and matching sound effect without unwanted repetition or staggering.
