IOT : WIRELESS SWITCHES CONTROL USING WEB SERVER
WITH ESP8266
About
the ESP8266
ESP8266 is a low cost Wi-Fi module. It
allows you to control
inputs and outputs as you would do with an
Arduino, but it comes with Wi-Fi.
It can be program using Arduino IDE. This
feature make it easy and great for IOT projects.
ESP8266
specifications
802.11 b/g/n protocol
Wi-Fi Direct (P2P), soft-AP
Integrated TCP/IP protocol stack
Built-in low-power 32-bit CPU
SDIO 2.0, SPI, UART
Installing
ESP8266Board
To install the ESP8266 board in your
Arduino IDE, follow these next
instructions:
1. On the Arduino IDE, click ‘’File’’ and
select ‘’Preferences’’
2. On the Preference page, enter
http://arduino.esp8266.com/stable/package_esp8266com_index.json
into Additional Board Manager URLs field and
press the “OK” button
3. Go to ‘’Tools’’ , ‘’Board
Boards Manager’’ ...
4. On Board Manager panel, scroll
down, select the ESP8266 board menu and Install “esp8266 by ESP8266 Community”
5. Then go to ‘’Tools’’ , ‘’Board’’ ,
‘’NodeMCU 1.0 (ESP-12E Module)’’ …
6. Finally, re-open your Arduino
IDE to ensure that it launches with the new boards installed.
Project ;
Connections ;
Besides Vcc and Gnd,
D1 – in relay 1 ( GPIO4 )
D2 – in relay 2 ( GPIO5 )
Copy code from below link and paste to
Arduino IDE
Next step ;
You need to modify the following two
variables with your network credentials,
so that your ESP8266 can establish a
connection with your router.
// Replace with your network credentials
const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password =
"REPLACE_WITH_YOUR_PASSWORD";
Then, upload the code.
After ‘’Done uploading’’ , open the Serial Monitor and press the ESP8266 RESET button. The ESP IP address will be generated on the Serial Monitor.
Open your phone browser, type the ESP IP address, and you’ll
see the following page. This page is sent by the ESP8266 when you make a
request on the ESP IP address.
With this page, you can turn on/off the relays using the
softkeys.
Happy trying :-)
