概述

• 使用树莓派、Arduino、语音模块、红外模块实现对家用空调进行控制
• 树莓派与Arduino进行TCP协议通信
• 树莓派与语音模块，Arduino与红外模块都进行串口通信

一、硬件组成

图1.树莓派

图2.Arduino

图3.语音模块

图4.红外模块

二、软件

图1.Arduino开发环境

图2.树莓派系统

图3.串口调试助手

三.获取空调遥控器红外编码

1、将红外模块与TTL串口相连接，并插入电脑USB口（注意管脚接线正确）

将需要被解码的空调遥控器按键对着红外模块按下，即在串口上返回所需要的解码数据（注意波特率，这里默认为115200）。

获取到红外编码后，将编码全部复制，以十六进制发送，红外模块对着空调，查看空调是否有反应。

四.树莓派与Arduino进行TCP协议通信

(1) 将Arduino做为服务端

#include <ESP8266WiFi.h>

char ssid[] = "1004";               /* wifi账号*/
char passwd[] = "13609618951";      /* 密码*/
int port = 8888;                    /* 端口号*/
WiFiServer server(port);            /* 设置服务器端口*/
