我的红外遥控时钟
本帖最后由 ttyp 于 2012-11-25 10:34 编辑这是我第一个实用的arduino成品。
使用DS1307为时钟模块，接VCC,GND,A4,A5
LCD1602为显示模块，接2，3，4，5，6，7脚
红外接收模块VS1838B，接11脚
使用红外遥控的mode按钮进入调整日期调整模式，power按钮退出，+，-按钮调整日期，play可以暂停日期，DHT11模块为可扩展模块，插上后在右下角会闪烁显示当前温度和湿度（可热插拔）
下面是代码：
/*
The circuit:
* LCD RS pin to digital pin 7
* LCD Enable pin to digital pin 6
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground
* 10K resistor:
* ends to +5V and ground
* DHT11 data to digital pin 11
* VS1838B data to digital pin 12
* DS1307 sda,sck to analog pin 4,5

下面是用到的库：
{:soso_e154:}求重新更新下附件。。前两天给论坛打安全补丁。。。没有修复附件上传部分。。结果文件没传到服务器上@@ 已经更新，可以下载了 程序好长。。。。。
