用Arduino写一个8266控制舵机的程序
以下是一个使用Arduino控制ESP8266模块控制舵机的示例程序：
#include <ESP8266WiFi.h>
#include <Servo.h>
// Replace with your network credentials
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
// Create a servo object
Servo myservo;
// Create a server object
WiFiServer server(80);
void setup() {
// Start serial communication
Serial.begin(115200);
// Connect to Wi-Fi network
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected successfully");
// Start the server
server.begin();
// Attach the servo to pin 5
myservo.attach(5);
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait for the client to send a request
Serial.println("New client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String request = client.readStringUntil('\r');
Serial.println(request);
client.flush();
// Parse the request to get the servo angle
int angle = request.substring(request.indexOf("=") + 1, request.indexOf("HTTP")).toInt();
Serial.println(angle);
// Set the servo angle
myservo.write(angle);
// Send a response to the client
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println("");
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<head><title>ESP8266 Servo Control</title></head>");
client.println("<body>");
client.println("<h1>ESP8266 Servo Control</h1>");
client.println("<form>");
client.println("Angle (0-180): <input type='text' name='angle'><br>");
client.println("<input type='submit' value='Submit'>");
client.println("</form>");
client.println("</body>");
client.println("</html>");
delay(1);
Serial.println("Client disconnected");
}
在此示例程序中，我们首先包含了ESP8266WiFi和Servo库。然后，我们定义了Wi-Fi网络的SSID和密码，并创建了一个WiFiServer对象和一个Servo对象。在setup()函数中，我们启动串行通信、连接到Wi-Fi网络、启动服务器并将舵机连接到引脚5。在loop()函数中，我们检查是否有客户端连接，然后等待客户端发送请求。我们从请求中提取角度值，将其设置为舵机角度，并向客户端发送响应。最后，我们延迟1毫秒并打印客户端断开连接的消息
