如果要按按鈕輸出一首音樂該怎麼做
#include "pitches.h"
int kunde[]={
NOTE_G5,NOTE_E5,NOTE_E5,NOTE_F5,NOTE_D5,NOTE_D5,NOTE_C5,NOTE_D5,NOTE_E5,NOTE_F5,NOTE_G5,NOTE_G5,NOTE_G5,
NOTE_G5,NOTE_E5,NOTE_E5,NOTE_F5,NOTE_D5,NOTE_D5,NOTE_C5,NOTE_E5,NOTE_G5,NOTE_G5,NOTE_C5};
int kunde_time[]={
500,500,1000,500,500,1000,500,500,500,500,500,500,1500,
500,500,1000,500,500,1000,500,500,500,500,1500};
int duration = 500; // 500 milliseconds
const int buttonPin = 2; // button pin
const int beePin = 13; // bee pin
// variables will change:
int buttonState = 0; // variable for reading the push button status
void setup() {
// initialize the BEE pin as an output:
pinMode(beePin, OUTPUT);
// initialize the push button pin as an input:
pinMode(buttonPin, INPUT);
}
void loop() {
// read the state of the push button value:
buttonState = digitalRead(buttonPin);
// check if the push button is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
for (int i= 0; i < 24; i++)
{
// 在 pin13 上輸出聲音，每個音階響 duration 豪秒
tone(beePin, kunde[i], kunde_time[i]);
// 間隔一段時間後再播放下一個音階
delay(kunde_time[i]+100);
}
// 兩秒後重新播放
delay(2000);
totalCount=0;
}
}
如果要按三次按鈕才輸出音樂呢
#include "pitches.h"
int kunde[]={
NOTE_G5,NOTE_E5,NOTE_E5,NOTE_F5,NOTE_D5,NOTE_D5,NOTE_C5,NOTE_D5,NOTE_E5,NOTE_F5,NOTE_G5,NOTE_G5,NOTE_G5,
NOTE_G5,NOTE_E5,NOTE_E5,NOTE_F5,NOTE_D5,NOTE_D5,NOTE_C5,NOTE_E5,NOTE_G5,NOTE_G5,NOTE_C5};
int kunde_time[]={
500,500,1000,500,500,1000,500,500,500,500,500,500,1500,
500,500,1000,500,500,1000,500,500,500,500,1500};
int duration = 500; // 500 milliseconds
int totalCount =0;
const int buttonPin = 2; // button pin
const int beePin = 13; // bee pin
// variables will change:
int buttonState = 0; // variable for reading the push button status
void setup() {
// initialize the Bee pin as an output:
pinMode(beePin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
}
void loop() {
// read the state of the push button value:
buttonState = digitalRead(buttonPin);
// check if the push button is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
totalCount++;
delay(500);
}
if(totalCount==3)
{
for (int i= 0; i < 24; i++)
{
// 在 pin13 上輸出聲音，每個音階響 duration 豪秒
tone(beePin, kunde[i], kunde_time[i]);
// 間隔一段時間後再播放下一個音階
delay(kunde_time[i]+100);
}
// 兩秒後重新播放
delay(2000);
totalCount=0;
}
}
