Wireless weather station - Mega2560 DHT11 and a

Hey guys can u please help me with wire and code wifi weather station with Arduino Mega 2560 DHT11 and wifi ESP8266 esp01 i found a lot of tutorials online but nothing works. When i wire the wifi shield i can see it in my iphone with name "Esp8266" but i can't broadcast nothing to server or even read the data from dht11. When i test dht11 with cable all good but with esp8266 not working. I think was connection timeout or something like that

Please post the code that does not do what you expect. tell what you expect tel what it did

post the schematic how everything is connected

what IDE do you use what OS do you use

....

ok i got no idea how is the right way to wire everything , so i start from scratch.

So here it is the connection betwen ESP8266 and Mega R3:

RX TO TX3 14,
VCC TO 3.3v,
GND TO GND,
TX TO RX3 15,
CH_PD TO 53

Here is the code witch i been try do do also with my password and name

/* ====== ESP8266 Demo ======
 *   Print out analog values
 * ==========================
 *
 * Change SSID and PASS to match your WiFi settings.
 * The IP address is displayed to soft serial upon successful connection.

Anyone please just tell me how to bloody wire them and what f@$*% code to upload without any errors and timeout xxxx just get rid off every single wire

Picture of what i got …
