ESP8266 ESP-01 Remote Multi Socket

Hardware :

1. (1) ESP8266 - ESP01

2. (1) Relay 220V (5V Control)

3. (1) Multi Socket

How to make :

See Above Photo

ESP8266 Programming :

• upload the following code to ESP-01
• Modify SSID and Password
• Modify Home Route Port Following to control it if you are outside.

 * 
 *  This sketch demonstrates how to set up a simple HTTP-like server.
 *  The server will set a GPIO pin depending on the request
 *    <a href="http://server_ip/gpio0" rel="nofollow">  http://server_ip/gpio0  </a> will set the GPIO0 high/low,
 *    <a href="http://server_ip/gpio2" rel="nofollow">  http://server_ip/gpio0  </a> will set the GPIO2 high/low
 *  server_ip is the IP address of the ESP8266 module, will be 
 *  printed to Serial when the module is connected.
 *  
 *  Before RUN :
 *                Change SSID and Password
 *                Change port number
 *
