How to use Arduino IDE with ESP8266 Support

When you download and install Arduino IDE already.

( Now is Arduino IDE version 1.6.5 )

Link to download https://www.arduino.cc/en/Main/Software

Then Open Arduino IDE

1. Go to menu File -> Preferences

Copy This link http://arduino.esp8266.com/stable/package_esp8266com_index.json

and paste to Additional Board Manager URLs Then OK

2.Go to Menu Tools -> Board -> Boards Manager...

You will see Boards Manager Windows.

Then type esp8266 in the Filter your search...

Now, It'show esp8266 information Then Click on that and it show INSTALL button.

Installing...

Installed

Now, It has ESP8266 Boards in your menu.

What is IOT Bluemix and IBM Internet of Things Foundation?

IBM Bluemix is an open-standards, cloud platform for building, running, and managing applications.

With Bluemix, developers can focus on building excellent user experiences with flexible compute options, choice of DevOps tooling, and a powerful set of IBM and third-party APIs and services.

IBM Internet of Things (IoT) Foundation and the capabilities for IoT development that are part of IBM Bluemix.

How to Send Sensor Data to IoT IBM Bluemix.

Do you have seen this video yet?

Edit some Arduino code

Your Mac Address xx xx xx xx xx xx
Your Internet Gateway 123.456.x.xxx
Your IP Address 123.456.x.xxx

Test your Arduino Code
Open Serial Monitor on Arduino IDE
Read temperature and humidity OK.
connect to d:quickstart:arduino:deedbafefeed OK.

Goto Web IBM Internet of Things Foundation
https://internetofthings.ibmcloud.com/

Quickstart Menu
Then copy your mac address to view your data

Now It's show your Data from Arduino and DHT11 Sensor

This is quickstart for demo.
Your can see the real time temperature and humidity sensor data graph but cannot save to database yet.

Set your SSID Network and Passwoard.

ThingSpeak https://thingspeak.com/

Make your TalkBack Command to control deives.
and make your Channel for show your Data.
Getting Start with ThingSpeak https://thingspeak.com/docs

ThingSpeak TalkBack API
To control devices use TalkBack API Command.

GET TalkBack Command

GET https://api.thingspeak.com/talkbacks/2225/commands/XX?api_key=1234567890ABCDEF

xx = COMMAND_ID ( 00 - 99 )

UPDATE TalkBack Command

PUT https://api.thingspeak.com/talkbacks/2225/commands/XX

Arduino ESP8266 Sent Sensor data to IoT ThingSpeak ( Internet of Things )

Arduino ESP8266 Sent Sensor data to IoT ThingSpeak

( Internet of Things )

A major component of or rather the very concept, Internet of Things, is about how to connect various devices to the network so that they can both send data and receive commands. Various technologies to address the last mile connectivity, such as Bluetooth, WiFi, NFC, etc... already exist, but most of these are complicated to deploy and often need additional hardware such as a local control server or appliance.

ThingSpeak https://thingspeak.com/

What is Thingspeak?
ThingSpeak is an open source “Internet of Things” application and API to store and retrieve data from things using HTTP over the Internet or via a Local Area Network. With ThingSpeak, you can create sensor logging applications, location tracking applications, and a social network of things with status updates.

Then we use ThingSpeak Channel to store and show your sensor data over Internet HTTP.
