• Feather HUZZAH with ESP8266
• Arduino IDE 1.8.2or higher
• Ubidots account - Educational License - Business License
  
• Ubidots library
• Ubidots account -or- STEM Licens

Begin by connecting your Feather HUZZAH ESP8266 to your computers USB port to configure the device.

1. Download the Arduino IDE if you not already have it. 1a. Open the Arduino IDE, select Files -> Preferences and enter the URL below into the Additional Board Manager URLs field. You can add multiple URLs by separating them with commas:

http://arduino.esp8266.com/stable/package_esp8266com_index.json

NOTE: If you're a Mac user, please note that in the Arduino software configurations are slightly different from Windows and Linux. Further, you may have to install the following driver to be able to upload your NodeMCU.

2. Open Boards Manager from Tools -> Board -> Boards Manager and install esp8266 platform. To simply find the correct device, search ESP8266 within the search bar.

3. Select your Adafruit Feather HUZZAH ESP8266 from Tools > Board menu. 4. Additionally, we need to be able to communicate with the Feather HUZZAH ESP8266 by selecting the proper port com. Go to Tools > Port > Select the appropriate PORT for your device.

5. To keep everything running fast and smooth - let's make sure the upload speed is optimized to 115200. Go to Tools > Upload Speed > 115200:

IMPORTANT NOTE:  Don't forget you will also need to install the SiLabs CP2104 Driver to be able to program the board properly. 

6. Close and REBOOT the Arduino IDE. 

7. Now with everything configured, UPLOAD the Blink Sketch to verify that everything is working properly. Go to File > Examples > Basics > Blink and compile the code. 

8. Once the code is properly updated the a red LED will start blinking.

9. Download and install the Ubidots library. For a detailed explanation of how to install libraries using the Arduino IDE, refer to this guide. 

With the following example, you will be able to simulate random readings taken from the Feather HUZZAH ESP8266 to Ubidots

1. To begin posting values to Ubidots, open the Arduino IDE and paste the sample code below. Once you have pasted the code, be sure to assign the following parameters:

• SSID (WiFi Name) & Password of the available network connection.
• Ubidots TOKEN

  /****************************************
   * Include Libraries
   ****************************************/
  
  #include "Ubidots.h"
  
  /****************************************
   * Define Instances and Constants
   ****************************************/
  
  const char* UBIDOTS_TOKEN = "...";  // Put here your Ubidots TOKEN
  const char* WIFI_SSID = "..."; // Put here your Wi-Fi SSID
  const char* WIFI_PASS = "..."; // Put here your Wi-Fi password
  
  Ubidots ubidots(UBIDOTS_TOKEN, UBI_HTTP);
  
  /****************************************
   * Auxiliar Functions
   ****************************************/
  
  // Put here your auxiliar functions
  
  /****************************************

   ****************************************/
  
  void setup() {
    Serial.begin(115200);
    ubidots.wifiConnect(WIFI_SSID, WIFI_PASS);
  
    // ubidots.setDebug(true);  // Uncomment this line for printing debug messages
  }
  
  void loop() {
    float value1 = random(0, 9) * 10;
    float value2 = random(0, 9) * 100;
    float value3 = random(0, 9) * 1000;
    ubidots.add("Variable_Name_One", value1);  // Change for your variable name
    ubidots.add("Variable_Name_Two", value2);
    ubidots.add("Variable_Name_Three", value3);
  
    bool bufferSent = false;
    bufferSent = ubidots.send("feather-huzzah");  // Will send data to a device label that matches the device Id
  
    if (bufferSent) {
      // Do something if values were sent properly
      Serial.println("Values sent by the device");
    }
  
    delay(5000);
  }

2. Verify your code within the Arduino IDE. To do this, in the top left corner of our Arduino IDE you will see the "Check Mark" icon press it to verify your code. 

3. Upload the code into your  Feather HUZZAH ESP8266. To do this, choose the "right-arrow"icon beside the check mark icon. 

4. To verify the connectivity of the device, open the serial monitor by selecting the "magnifying glass" icon in the top right corner of our Arduino IDE. 

5. Confirm your data in Ubidots. Now you should see the published data in your Ubidots account, locate the device called "feather-huzzah" and visualize your data.

With this simple tutorial we are able to POST data to Ubidots with the ease of the Arduino IDE and a Feather HUZZAH with an ESP8266. If your desire send more than one variable to Ubidots, reference Ubidots REST API to learn how to build the request properly. :) 

Now its time to create Ubidots Dashboards to visualize your data and deploy your internet connected monitoring solution!
