IoT Platforms - Adafruit IO

An online platform is integral to IoT devices. I look at Adafruit IO as a popular option for data collection and device management.

The best video on ada.io yet. great explanation of the hierarchy.

[@PabloAlvarado-ut3qu]

Great Video!! Thanks for explained it!! //Muchas gracias por explicarlo!

[@nonos439]

Today I used the code on the first example, and it worked!

[@avrphreak9121]

Thank you for this explanation! Have you been able to get the Adafruitio route you initially tried on the esp32 working?
Other than that, great video and normally paced as well! Makes following along so much easier.

I never went back to that example until today. I find using the standard MQTT libraries a lot easier to use and understand.
That said, I went back to the example today. I was able to compile and upload the code to my ESP32 without the errors I saw in the video. However, I wasn't able to connect to Adafruit IO. A lot has changed though, so I may be missing a step.

[@webslinger2011]

Had my arduino library stored on a different drive. It puts my libraries there as default for some reason. Even after installing the new arduino version. So I copied over the whole library to that old library folder then added ArduinoHttpClient, Adafruit_MQTT_Library and Adafruit_IO_Arduino... It was able to finish compiling your first tutorial. Your MQTT demo works.

Fantastic, efficient use of my time. Got me going in a few minutes. Thanks! I do wish the Adafruit map integration had the ability to plot data at the points on it. It seems kind of simple. Not sure if you mentioned it, but the fact that you need to end your feed connection string with /csv if you want to pass location along with value data. Otherwise it just comes across as value data.

[@BasementElectronics]

I'm glad the video helped.
Admittedly, I haven't sent data that complex to Adafruit IO yet. The /csv is a good tip that would have stumped me if I had run across it.

[@silviocorrea25]

Hey, great video!!! Please, I'm already using Adafruit, but I need my ESP32 to update values when it starts, and not only when the buttons are clicked. Can I do that somehow? Thanks!!!

[@abhirupbera804]

Sir,
How to send one digital input and receive one digital output? Say, we have two esp8266 through adafruit broker. One esp digital input will make another esp digital output high and vice versa. Please help me out.

[@MightyTechGuy]

You can update the esp version to latest such as 2.6.3 using boards manager, then the first part will work :)

[@BasementElectronics]

I just noticed this while putting the code together for GitHub. Thank you for the update.

[@vsdeebanmurugan7542]

while running ,cant able to connect to the mqtt server ,guide me to solve the problem

[@BasementElectronics]

I recommend getting a utility called MQTT.fx
I've been using it lately to test a few other MQTT data brokers. It's pretty simple and a good way to test your connection. Once you are confident on your connection information (SSL, credentials, server, etc.), you have one less thing to worry about in your program.
For my sake, I just loaded my Adafruit.IO information into the application and confirmed nothing has changed since I originally recorded this.

[@BenDover-pq8xj]

Good job of explaining that, you have convinced me to roll on by. Node Red will be far better in both transfer of data and the widget graphics look, they really are lame looking graphics. Many thks again.

[@BasementElectronics]

I'm glad you found the video useful.
I've been hearing a lot of things about Node Red lately. I think I need to put it on my list of things to investigate.

[@aravindanvenkatesh8836]

Send me the code ....

[@BasementElectronics]

The code I used were examples that came with the libraries (with very few changes).
If you still need the code, let me know and I'll upload it to my GitHub.

[@ranga-srilbt5816]

@@BasementElectronics plz send me a code of the board esp32 of this program

[@BasementElectronics]

I have added a link to the code in GitHub in the description.
I also changed the MQTT example to use ESP32 instead of ESP8266. To do this, I just needed to change which WiFi.h library to include. You'll see the old one (commented out) and the new one in the example.
