- Fri Jul 21, 2017 8:19 pm #68434 Hello guys, Im 15y old and I have never ever tried programming so this is my first experience with this in Arduino IDE Im just trying to copy some codes and edit them so I can make what I want but now Im really stucked:
#include <SoftwareSerial.h>
#include <Servo.h>
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>

const char *ssid = "MojeServa";
const char *password = "";
ESP8266WebServer server(80);

void handleRoot()
{
server.send(200, "text/html", "<h1>You are connected</h1>");
}


SoftwareSerial esp8266(5, 4); /

//define variables
#define DEBUG true //display ESP8266 messages on Serial Monitor
#define SERV1 D1
#define SERV2 D2

Servo s1; //servo 1
Servo s2; //servo 2
int pos1 = 90; //servo 1 current position
int pos2 = 90; //servo 2 current position
int vel = 10; //servos' speed (100 -> 90º in 1 s)(1 -> 90º in 9 s)
int pos1min = 0; //servo 1 minimum position
int pos2min = 0; //servo 2 minimum position
int pos1max = 180; //servo 1 maximum position
int pos2max = 180; //servo 2 maximum position

--------------------- I want to make a programme which will receive data packages from my phone, but first ive got to make an AP from my esp8266 when i upload the code to the esp8266 i can see my wifi "mojeserva" just for a while but i cant even connect ... and then it dissapears i really dont know what to do so i will welcome any help ...
