Iot Servo Slider

Pour commander l'asservissement par le curseur sur l'application

This app used to control the servo from iot device that run arduino ide, for example nodeMCU, Wemos, ESP8266.

Below the code for the arduino:

#include

#include

Servo servo;

const char* ssid = "WIFI_SSID"; // Enter Your wifi SSID here

const char* password = "WIFI_PASSWORD"; // Enter Your Wifi Password Here

ESP8266WebServer server(80);

//The function we want to call

void slider(){

// Serial.println(server.args()); //to known number of parameter

// Serial.println(server.argName(i)); //Get the name of the parameter

Serial.println(server.arg(0)); //Print value receive

int val = server.arg(0).toInt(); //Servo write only read integer

servo.write(val);

}

//The function if no function found

void handleNotFound(){

String message = "File Not Found\n\n";

message += "URI: ";

message += server.uri();

message += "\nMethod: ";

message += (server.method() == HTTP_GET)?"GET":"POST";

message += "\nArguments: ";

message += server.args();

message += "\n";

for (uint8_t i=0; i message += " " + server.argName(i) + ": " + server.arg(i) + "\n";

}

server.send(404, "text/plain", message);

}

void setup() {

Serial.begin(115200);

WiFi.begin(ssid, password);

Serial.println("");

// Wait for connection

while (WiFi.status() != WL_CONNECTED) {

delay(500);

Serial.print(".");

}

Serial.println("");

Serial.print("Connected to ");

Serial.println(ssid);

Serial.print("IP address: ");

Serial.println(WiFi.localIP());

if (MDNS.begin("esp8266")) {

Serial.println("MDNS responder started");

}

//Set the option when we put at url

//the slider function will be called

server.on("/Slider",slider);

//When input the IP address on url

server.on("/", [](){

server.send(200, "text/plain", "this works as well");

});

server.onNotFound(handleNotFound);

server.begin();

Serial.println("HTTP server started");

servo.attach(D3);

}

void loop() {

server.handleClient();

}
