How to use StickC Plus beeper buzzer about m5unified

[lovyan03]

Hello, @patfelst
The buzzer built into the StickCPlus is very small, so it doesn't make a loud sound

It may be easier to see how it works by playing it repeatedly in a loop. Try the following code:

#include <M5Unified.h>

void setup() {
  M5.begin();
  M5.Speaker.setVolume(255);
}

void loop()
{
  for (int i = 1000; i < 8000; ++i) {
    M5.Speaker.tone(i, 100,0);
    M5.Display.drawNumber(i, 0, 0);
  }
}

Yes that solved the problem, thank you so much. It is very quiet like you say. Have a nice day @lovyan03.
