1、先來段視頻看看效果
2、基本原理
（1）幾個控制器通過wifi連接到AP上，組成局域網。
（2）控制器基於arduion，使用了串口轉wifi模塊，它在控制器上建立了一個TCP服務器。控制端通過調用TCP服務來達到控制的目的。
下面分別介紹各個控制器。
3、電燈控制器
（1）硬件構成
arduino模塊+wifi模塊+繼電器模塊。
繼電器模塊的AC端接到零線開關上。
（2）Arduino代碼
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); //將收到是數據再通過串口發送出去 //delay(1000); } }

（1）硬件構成
arduino模塊+wifi模塊+場效管模塊+自制的穩壓模塊。
我的鎖是電控鎖，它里面有一個線圈，當線圈通電后，它中間的鋼芯被磁化，吸位鎖的卡扣，門就開了。由於線圈在通電時的瞬間電流較大，為避免它對電路的其它部分造成干擾（可能會造成控制器死機），加上一個自制的穩壓模塊。穩壓模塊由一些電感和電容組成。

void setup() { Serial.begin(115200); pinMode(2,OUTPUT); digitalWrite(2, LOW); // 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 // delay(1000); digitalWrite(2, HIGH); // switch off } else if(val == '0') { digitalWrite(2, LOW); // switch off } Serial.print(val); //將收到是數據再通過串口發送出去 //delay(1000); } }
