Nowadays, we are connected “things” by using an inexpensive WiFi module from Espressif known as “ESP8266 module”.
This WiFi module have many mounted on MCU board for prompt to use in any project and application.
Today, we are show you how to send data to display from Internet of Things device running by Node MCU.
Send data via ESP8266 wifi to “IoTtweet” dashboard.

[Preparing]
- Node MCU board (In this example, we use Node MCU version 0.9, built-in ESP8266 WiFi module)
- Arduino IDE
- User account “IoTtweet.com”. (If you are not have, sign up now)
- IoTtweet library. (You can download it as zip file from Github)
- "ESP8266WiFi.h" and "AduinoJson.h" library

[Start]

1. Sign up IoTtweet.com
You can sign up here, and after got account, go to Dashboard > My IoT garage. You must register your device, and get individual key.


"My IoT garage" button

2. Install library

* ESP8266WiFi.h
- Arduino IDE, open preferences on menu.
- Add link http://arduino.esp8266.com/stable/package_esp8266com_index.json in Board Manager urls.
- Save and restart Arduino IDE.
- Go to Tool > Boards > Boards Manager, scroll down and install package “esp8266 by ESP8266 community”.
- Restart Arduino IDE again.
- Finished.

* ArduinoJson.h
- Arduino IDE, open Sketch > Include Libraries > Manage Libraries on menu.
- Search "ArduinoJson" and make install.
- Finished.

* IoTtweet.h
- Download IoTtweet library from Github
- Extract file
- In folder “src”, copy folder name “IoTtweet” and paste in folder Arduino > libraries
- Finished.
