使用任意红外遥控器和Arduino及继电器控制交流灯泡
在本教程中，我们将学习如何使用红外遥控器通过Arduino和继电器模块来操作交流灯泡。该项目涉及解码遥控器的信号，并利用这些信号控制继电器，从而开启和关闭交流灯泡。在本教程结束时，您将能够使用任何红外遥控器来控制您的灯具。
我们将使用红外接收器捕捉遥控器发出的信号，Arduino 将解读这些信号以执行特定操作。提供的代码将允许您选择遥控器的类型（黑色或白色）以及您是使用 PCB 还是裸模块作为接收器。请确保观看相关视频以获取更多细节和说明（在视频中为 :00）。
硬件解析
对于这个项目，主要组成部分包括Arduino主板、红外接收模块和继电器模块。红外接收器负责捕获来自遥控器的信号并将其发送到Arduino。继电器模块作为开关来控制交流灯泡，根据接收到的信号实现开关操作。
红外接收器通常在38 kHz的频率下工作，可以从约10到15米的距离检测信号。一旦Arduino接收到信号，它会对其进行解码，并使用继电器控制灯泡的电源。
接线说明
开始接线，将红外接收模块连接到Arduino。接收器的VCC引脚连接到Arduino的5V引脚，接地引脚连接到GND引脚。红外接收器的信号引脚应连接到数字引脚。11在 Arduino 上。
接下来，连接继电器模块。继电器的控制脚应连接到数字脚2在Arduino上。同时，将继电器的VCC和GND引脚分别连接到Arduino的5V和GND。最后，根据继电器的规格将AC灯泡接到继电器上，以确保安全操作。
代码示例与教程
在程序的设置阶段，我们初始化串行通信并设置继电器引脚。标识符RECV_PIN设置为11这就是红外接收器的信号针连接的地方。这使我们能够接收来自遥控器的数据。
void setup() {
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver
pinMode(RELAY_PIN, OUTPUT); // define a pin for relay as OUTPUT
digitalWrite(RELAY_PIN, HIGH); // set relay to OFF at the beginning
}在循环函数中，我们不断检查来自遥控器的信号。当检测到信号时，值被解码，并根据按下的键采取相应的行动。
void loop() {
if (irrecv.decode(&results)) {
Serial.println(results.value, HEX); // Print the received value
robojaxValidateCode(results.value); // Validate the code
irrecv.resume(); // Receive the next value
}
delay(100);
}翻robojaxValidateCode该函数将接收到的代码与遥控器的已知值进行检查。根据按下的按键，它将使用继电器执行相应的操作。
void robojaxValidateCode(int cd) {
if (type == 'W' && !PCB) {
// Check White remote codes
for (int i = 0; i < sizeof(whiteRemote) / sizeof(int); i++) {
if (whiteRemote[i] == cd) {
Serial.print("Key pressed: ");
Serial.println(whiteRemoteKey[i]);
relayAction(whiteRemoteKey[i]); // Take action
}
}
}
}在这个函数中，代码检查按下的键是否对应于定义的数组值。如果找到匹配，它将调用relayAction根据按下的键将继电器打开或关闭的功能。
演示 / 期待什么
完成布线并上传代码后，您可以使用红外遥控器控制 AC 灯泡。按下遥控器上的指定键，继电器应相应地激活或停用灯泡。确保测试每个按键以查看其响应（视频时长 5:00）。

138-Source for controlling an AC load using an Arduino
语言: C++
/*
* Original library from - http://arcfn.com
*
* This Arduino code decodes any remote code and then you can control an AC load using a relay
* sold on eBay for Arduino.
* You have to select the type of your remote as Black or White in the code below
* and also select your receiver 1838 as either a PCB or bare module. See video for details
*
* You have to watch this video: https://youtu.be/muAkBQb24NI
* before proceeding with this code.
