 Thank you for opening an issue on an Adafruit Arduino library repository.  To
 improve the speed of resolution please review the following guidelines and
 common troubleshooting steps below before creating the issue:
 - **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
  something isn't working as expected.  In many cases the problem is a common issue
  that you will more quickly receive help from the forum community.  GitHub issues
  are meant for known defects in the code.  If you don't know if there is a defect
  in the code then start with troubleshooting on the forum first.
 - **If following a tutorial or guide be sure you didn't miss a step.** Carefully
  check all of the steps and commands to run have been followed.  Consult the
  forum if you're unsure or have questions about steps in a guide/tutorial.
 - **For Arduino projects check these very common issues to ensure they don't apply**:
  - For uploading sketches or communicating with the board make sure you're using
    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
    very hard to tell the difference between a data and charge cable!  Try using the
    cable with other devices or swapping to another cable to confirm it is not
    the problem.
  - **Be sure you are supplying adequate power to the board.**  Check the specs of
    your board and plug in an external power supply.  In many cases just
    plugging a board into your computer is not enough to power it and other
    peripherals.
  - **Double check all soldering joints and connections.**  Flakey connections
    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
  - **Ensure you are using an official Arduino or Adafruit board.** We can't
    guarantee a clone board will have the same functionality and work as expected
    with this code and don't support them.
 If you're sure this issue is a defect in the code and checked the steps above
 please fill in the following fields to provide enough troubleshooting information.
 You may delete the guideline and text above to just leave the following details:
 - Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
 - Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
  VERSION HERE**
 - List the steps to reproduce the problem below (if possible attach a sketch or
  copy the sketch code in too): **LIST REPRO STEPS BELOW**

 Thank you for creating a pull request to contribute to Adafruit's GitHub code!
 Before you open the request please review the following guidelines and tips to
 help it be more easily integrated:
 - **Describe the scope of your change--i.e. what the change does and what parts
  of the code were modified.**  This will help us understand any risks of integrating
  the code.
 - **Describe any known limitations with your change.**  For example if the change
  doesn't apply to a supported platform of the library please mention it.
 - **Please run any tests or examples that can exercise your modified code.**  We
  strive to not break users of the code and running tests/examples helps with this
  process.
 Thank you again for contributing!  We will try to test and integrate the change
 as soon as we can, but be aware we have many GitHub repositories to manage and
 can't immediately respond to every request.  There is no need to bump or check in
 on a pull request (it will clutter the discussion of the request).
 Also don't be worried if the request is closed or not integrated--sometimes the
 priorities of Adafruit's GitHub code (education, ease of use) might not match the
 priorities of the pull request.  Don't fret, the open source community thrives on
 forks and GitHub makes it easy to keep your changes in a forked repo.
 After reviewing the guidelines above you can delete this text from the pull request.

 /* Adafruit IO Example Using WiFiManager with Custom Adafruit IO parameters
 *
 * This is a simple Adafruit feed subscribe example that uses
 * WiFiManager to handle setup of WiFi credentials and connecting
 * to the network instead of defining the WiFI SSID and password
 * explicitly in the code.
 *
 * In addition, this example allows you to enter your Adafruit IO username and key
 * as customer parameters in WiFiManager so that they do not need to be coded into
 * the sketch.
 * 
 * This is useful if you want to create projects and share them with others that
 * may use them on a different WiFi network and use a different Adafruit IO account
 * for IOT integrations such as collecting sensor data or voice command integration via
 * IFFT.
 *
 * To use this example, setup a feed called "myfeed".  When the ESP8266 or ESP32
 * microcontroller starts, join the "WiFi Setup" SSID and you should be presented
 * with the config portal.  If the config portal does not automatically start you
 * can browse to http://192.168.4.1 to access it
 *
 * Select the SSID and enter the password for WiFi Access in the config portal.
 * Enter your Adafruit IO username and key in the config portal and select "Save".
 *
 * When you manually add data to the feed on io.adafruit.com, you'll see
 * that data written to the serial output.
