void loop(){ if(bt.available()){ char databt = bt.read(); //字節 if(datab

請問我的程式裡括號的部分是錯在哪呢,一直找不到答案…

#include <DHT.h>

#include <DHT_U.h>

void setup() {

#include “DHT.h”

#define dhtPin 2 //讀取DHT11 Data

#define dhtType DHT11 //選用DHT11

#define FAN 8

#define HOT 9

#define PERIOD1 106060*1000 // this is in milliseconds

#define PERIOD2 156060*1000 // this is in milliseconds

#define PERIOD3 256060*1000

// millis() returns an unsigned long so we’ll use that to keep track of time

unsigned long lastTime = 0;

/*

控制溫度的程式

10分鐘維持80度

15分鐘維持70度

25分鐘維持60度

*/

DHT dht(dhtPin, dhtType); // Initialize DHT sensor

int stage = 0;

float t;

void setup() {

Serial.begin(9600);//設定鮑率9600

pinMode(FAN, OUTPUT);

pinMode(HOT, OUTPUT);

digitalWrite(FAN, LOW);

digitalWrite(HOT, LOW);

dht.begin();//啟動DHT

lastTime = millis();

stage = 80;

}

void up()

{

if (stage >= t - 3)

{

digitalWrite(FAN,HIGH);

digitalWrite(HOT,LOW);

}

否則(階段<= t-3)

{

digitalWrite(FAN,HIGH);

digitalWrite(HOT,LOW);

}

其他

{

digitalWrite(FAN,LOW);

digitalWrite(HOT,LOW);

}

}

無效循環()

{

t = dht.readTemperature(); //讀取攝氏溫度

float f = dht.readTemperature(true); //讀取華氏溫度

如果(isnan(h)|| isnan(t)|| isnan(f)){

Serial.println(“無法從DHT傳感器讀取!”);

返回;

}

unsigned long now = millis();

if(now-lastTime> = PERIOD1)//每隔PERIOD毫秒為一次

{

階段= 80;

}

否則if(now-lastTime> = PERIOD2)//每隔PERIOD毫秒為一次

{

階段= 70;

}

else if(now-lastTime> = PERIOD3)//每隔PERIOD毫秒為一次

{

階段= 60;

}

}

}
