yawot your action weakness of technology.

Control your device anywhere in the world is not easy task but technologies achieve every second new achievement so today its possible to control your device anywhere in the world....

esp8266/wemosd1/node mcu any of these board are enabling to control your devices over the internet

Esp8266 and Other wifi shield is enabled to control devices over the internet.

how its work.

Esp8266 and control devices not connected to wired but both connected to internet or wifi connection so means that both are connected to each other.when I toggle the web button then its web button signal goes to server and server signal goes to receiver side . when tx signal d1 =1 then d1 is on when toggle switch d1=0 then d1 is off.

how to download and upload esp8266 code.

first, download or copy-paste the given code. // this file is created by yawot.com //author name: Rahulpunk

Before upload to the board edit the code some important instruction.

1.char auth[] = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

2.//Replace your wifi credentials here

3.const char* ssid = "yourwifiusername" write wifi user name;

4.const char* password = "password" wifi password change as per your connection;

5.unsigned long channel = xxxxxx;// thingspeak channel id write
