 ESP8266 firmware 
You need to upload new firmware to your ESP8266 Module.
Download Firmware from ESPDUINO  https://github.com/tuanpmt/espduino

Firmware is in folder espduino-master/esp8266/release/
It has 2 files .
0x00000.bin
0x40000.bin




Arduino Code 

 Original Code from 
Rock solid esp8266 wifi mqtt, restful client for arduino
http://tuanpm.net/rock-solid-esp8266-wifi-mqtt-restful-client-for-arduino/

But,I've modified to control device with ThingSpeak.com

Arduino Code Download V0.2
www.softpowergroup.net/files/Arduino/thingspeak_Control2.zip


Code are need some edit.
Set your SSID Network and Passwoard.






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
    api_key=1234567890ABCDEF
    command_string=OPENDOOR
    position=5

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.

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.

ESP8266 Firmware Update with Arduino Board



ESP8266 Firmware Update with Arduino Board
The ESP8266 module is a cheap Wireless module.It has SOC(system on chip) that can handle TCP protocols. By default, these modules come with an AT command processor and can act as a serial to WiFi bridge. There is lots of info on the web about this module.



Some Application need to flash firmware.

So,I try to update firmware with Arduino Board.


Hardware

  1. ESP8266 WiFi Module ( we use ESP-01 )
  2. Arduino UNO Board
  3. Logic Level converter
and some jumper cable.



Wiring Diagram

Normal Arduino is 5V supply must use level converter. 

If use Arduino 3.3v ,so don't need level converter.



Software 
  1. Arduino IDE with Set upload mode code
  2. ESP Flash Download Tool V0.9.3.1
  3. Firmware bin file ( xxx.bin )


Arduino IDE 1.x.x and Set Upload Mode code

 Arduino Code for Set ESP8266 Upload Mode

     int ch_pd = 3;
     int io0 = 2;

     void setup() {
       pinMode(ch_pd, OUTPUT);
       pinMode(io0, OUTPUT);
       digitalWrite(io0,LOW);
       digitalWrite(ch_pd, LOW);
       delay(1000);
       digitalWrite(ch_pd, HIGH);
     }

     void loop()
     {
      
     }
