Arduino play many piezo at once

Question

I need to play sound on 10 piezos at once. How to do that without delay() function.

Use the blink-without-delay pattern https://www.arduino.cc/en/Tutorial/BlinkWithoutDelay, a TimeMarker https://github.com/mikaelpatel/Arduino-Timemark or a Scheduler https://github.com/mikaelpatel/Arduino-Scheduler — Mikael Patel, Mar 07 '17 at 13:20

You can attach up to 10 events to each Timer object you declare. That will suit your use case.

Post a code please. – Lowder Mar 09 '17 at 13:33
Why this code not work? `long ids[10]; void playNote(int pin, unsigned long freq) { int ms = 1000/freq; ids[pin] = t.oscillate(pin, ms / 2, HIGH); } void stopNote(int pin) { t.stop(ids[pin]); }` – Lowder Mar 09 '17 at 13:40
Post a new question with your full code and not just a snippet, You'll get much better help. I'll also participate. – Enric Blanco Mar 09 '17 at 15:58
