hi..
im new at this, so sorry if im doing a lot of stupid questions..
im doing a project where i use 2 shift registers to control 14 LEDs and i also want to play a song using a buzzer but when i try to do that at the same time, it just plays the song and only then the LEDs work. I tried to use your library because i thought it could be because of timers but it doesnt work anyway.. what can i do ?
