arduino使用1个按键、1个LED灯和1个喇叭，设计一个利用按键控制喇叭声响和灯亮灭的作品（英文名为：ButtonLedTone），具体要求如下： Ÿ按一次按键，灯亮；再按一次按键，灯灭；一直如此循环； Ÿ每次按下按键，喇叭都会响一下（约100毫秒），声音要清脆响亮； Ÿ要做按键去抖动功能，确保对按键状态变化的准确判断。

Sure, I can help you with that! Here's the code for the ButtonLedTone project using an Arduino board:

int ledPin = 13; // LED connected to digital pin 13
int speakerPin = 8; // Speaker connected to digital pin 8
int buttonPin = 2; // Button connected to digital pin 2
int buttonState = 0; // variable for storing button state
int lastButtonState = 0; // variable for storing last button state
int toneDuration = 100; // duration of tone in milliseconds

void setup() {
  pinMode(ledPin, OUTPUT); // set LED pin as output
  pinMode(speakerPin, OUTPUT); // set speaker pin as output
  pinMode(buttonPin, INPUT); // set button pin as input
}

void loop() {
  buttonState = digitalRead(buttonPin); // read button state
  if (buttonState != lastButtonState) { // check for button state change
    delay(10); // debounce delay
    buttonState = digitalRead(buttonPin); // read button state again
    if (buttonState == HIGH) { // button pressed
      digitalWrite(ledPin, !digitalRead(ledPin)); // toggle LED state
      tone(speakerPin, 1000, toneDuration); // play tone
    }
  }
  lastButtonState = buttonState; // store last button state
}

This code uses the `digitalRead()` function to read the state of the button connected to pin 2. It also uses the `digitalWrite()` function to toggle the state of the LED connected to pin 13 and the `tone()` function to play a tone on the speaker connected to pin 8. The `delay()` function is used to debounce the button and ensure accurate state change detection.

I hope this helps! Let me know if you have any other questions.
