1、先来段视频看看效果
2、基本原理
(1)几个控制器通过wifi连接到AP上,组成局域网。
(2)控制器基于arduion,使用了串口转wifi模块,它在控制器上建立了一个TCP服务器。控制端通过调用TCP服务来达到控制的目的。
下面分别介绍各个控制器。
3、电灯控制器
(1)硬件构成
arduino模块+wifi模块+继电器模块。
继电器模块的AC端接到零线开关上。
(2)Arduino代码

void setup() { Serial.begin(115200); pinMode(2,OUTPUT); digitalWrite(2, HIGH); // switch off } void loop() { // delay(500); if (Serial.available() > 0) { char val; val = Serial.read(); // read serial data if(val == '1') { digitalWrite(2, LOW); // switch on } else if(val == '0') { digitalWrite(2, HIGH); // switch off } Serial.print(val); //将收到是数据再通过串口发送出去 //delay(1000); } }

(1)硬件构成
arduino模块+wifi模块+场效管模块+自制的稳压模块。
我的锁是电控锁,它里面有一个线圈,当线圈通电后,它中间的钢芯被磁化,吸位锁的卡扣,门就开了。由于线圈在通电时的瞬间电流较大,为避免它对电路的其它部分造成干扰(可能会造成控制器死机),加上一个自制的稳压模块。稳压模块由一些电感和电容组成。
