最近發現自己沒有個小鐘表起床看時間不方便于是就做了一個
成品！

材料arduino
   ds1302
   1602  （有條件的可以使I2c）
   dht11
   電線若干

接線順序
1602---12 ，11 ，7  ,6  ,5  ,4
ds1302 ce--2
            Io--3
            sclk--9dht11----8

使用3個庫LiquidCrystal.h  DS1302.h dht11.h
直接上原碼，沒有按鍵調時，和串口功能，以后改進

#include <LiquidCrystal.h>
#include <DS1302.h>
#include <dht11.h> // DHT11 傳感器程序庫
// Init the DS1302
DS1302 rtc(2, 3, 9);
// Init the LCD
LiquidCrystal lcd(12, 11, 7, 6, 5, 4);
void setup()
{
// Set the clock to run-mode, and disable the write protection
rtc.halt(false);
rtc.writeProtect(false);
// Setup LCD to 16x2 characters
lcd.begin(16, 2);
// The following lines can be commented out to use the values already stored in the DS1302
rtc.setDOW(TUESDAY); // Set Day-of-Week to FRIDAY
rtc.setTime(22,05, 0); // Set the time to 12:00:00 (24hr format)
rtc.setDate(24,10,2017); // Set the date to August 6th, 2010
}
void loop(){
// Display time centered on the upper line
lcd.setCursor(1, 0);
lcd.print(rtc.getTimeStr());
// Display abbreviated Day-of-Week in the lower left corner
lcd.setCursor(12, 0);
lcd.print(rtc.getDOWStr(FORMAT_SHORT));
// Display date in the lower right corner
lcd.setCursor(6, 1);
lcd.print(rtc.getDateStr());
// Wait one second before repeating :)
delay (1000);
dht11 DHT11; // 溫濕度傳感器程序對象
const byte dataPin = 8;
int chk = DHT11.read(dataPin);
if (chk == 0)
lcd.setCursor(0, 1); // 顯示溫度
lcd.print((float)DHT11.temperature, 1);
lcd.print((char) 0xDF);
}
