好的,以下是基于DS3231实时时钟模块的Adrino Uno闹钟的完整代码:
```c++
#include <Wire.h>
#include "RTClib.h"
RTC_DS3231 rtc;
int alarmHour = 7;
int alarmMinute = 30;
bool alarmTriggered = false;
void setup() {
Serial.begin(9600);
Wire.begin();
rtc.begin();
if (! rtc.isrunning()) {
Serial.println("RTC is NOT running!");
rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
}
rtc.clearAlarm(1);
rtc.disableAlarm(1);
rtc.clearAlarm(2);
rtc.disableAlarm(2);
rtc.setAlarm1(DateTime(0, 0, 0, alarmHour, alarmMinute, 0), DS3231_A1_Hour);
rtc.enableAlarm(1);
}
void loop() {
DateTime now = rtc.now();
int hour = now.hour();
int minute = now.minute();
int second = now.second();
if (hour == alarmHour && minute == alarmMinute && !alarmTriggered) {
Serial.println("Alarm Triggered!");
alarmTriggered = true;
}
if (hour != alarmHour || minute != alarmMinute) {
alarmTriggered = false;
}
delay(1000);
}
```
该代码首先连接DS3231实时时钟模块到Adrino Uno板子上。然后设定闹钟时间为7:30,并启用闹钟。在无限循环中,它读取实时时钟模块的时间,并将其与闹钟时间进行比较。如果当前时间与闹钟时间相同且闹钟尚未触发,则触发闹钟并将"alarmTriggered"变量设置为true。如果当前时间与闹钟时间不同,则将"alarmTriggered"变量设置为false,以便下一次闹钟触发。
希望这可以帮助您实现一个基于DS3231实时时钟模块的Adrino Uno闹钟。
