This is so much useful, thanks you so much, i was building something like this and this video help me with that http client bug LOL

[@makeratplaycoding2666]

Glad it helped!

love your work!!! :p

[@makeratplaycoding2666]

Thanks

[@christophhelms4905]

Great, thanks for the thorough walkthrough. I'm just working on the same idea but for Raspberry Pi and I have a ESP32 on the way to try out your project. To get the "Next song" feature working might be tricky... I guess you need code that checks if the RFID tag is continuously read (which means ignore these calls). If it stops being read for a certain interval, we can read it as a new tag. Just in general, is everything else still working for you or did the API change?

[@maguiresciberras1247]

Hey mate, love your work. I'm building a similar device for which I've written the code. The only part I haven't written is the Spotify API library. I'm encountering an issue: on the first boot, I need to have Alexa already playing, otherwise the device ID becomes outdated. I'm also using the device name; I get the player details and then grab the device ID based on the specified device name. However, this doesn't seem to work unless Alexa is playing first. After that initial step, I have no more issues. I can play on my phone and then hit play on my little device, and it will transfer and work fully as intended. It's just that initial boot that's problematic.

[@luigicicatiello3991]

That's awesome. Thanks a lot for you sharing it. just to ask, is there a reason to use vs code/arduino-cli and not vs code/platformIO? Keep up the great work!

[@makeratplaycoding2666]

They all achieve the same end goal of putting a program on your microcontroller. They each just offer different helping tools to get you there. I like VS Code because I use it to program for other platforms as well like windows, web, AWS. I don't have to learn a new IDE/Tool set each time I switch target platforms.

[@Ivance1]

You are incredible

[@makeratplaycoding2666]

Thanks for the kind words.

[@moetij]

This is awesome. I knew I kept all my records, cassettes, and cd's for a reason. Ordered the parts and got the info needed from spotify. New to Visual Studio Code, how do I flash the code to the ESP32?

[@makeratplaycoding2666]

Glad it inspired you to build your own. Share your results. Would love to see how it turned out.

[@DrMohammadArifulHoque]

I have two questions. 1. How to write the links on rfid cards. 2. My serial monitor only shows nfc card present. Nothing else is happening. What am I doing wrong?

[@nerissacheung]

Hi! Thanks for the code, i watched the video but probably didnt understand how to deal with the deviceName. Can you help me?

[@makeratplaycoding2666]

In my example I had to use the device_id query parameter to ensure that Spotify played the music on the echo dot I wanted since I have multiply devices connected to my Spotify account. I believe you can make the API calls without the device Id and Spotify will just default to the last device that was playing Spotify music. If you give me a more detailed question, I might be able to help.

[@Kodiak1806]

do you have a video creating projects and importing libraries like wifi.h into visual studio code?

[@makeratplaycoding2666]

I have not created a video on that topic. I assume it is something you are interested in. Exactly what are you wanting to understand?

i am getting a return 400 and return 403 on the spotify nfc project. what do i set for redirect upi's?

[@makeratplaycoding2666]

Did you create yourself an app in the Spotify Dashboard? For the code ESP32 it doesn't matter what the redirect url is as long as you use the same when in the api calls that you used when you created the app in the Spotify Dashboard.

[@MPElectronique]

You are not implementing Auth 2.0 in your code?

[@hendrikj5169]

do the code to which it redirects one after providing redirect_url and clientId and the refresh token expire? I got my redirect token using Spotifys own example in GitHub aß well as your application from the other video but i cant get it to work. it always says "failed to connect to..."

[@makeratplaycoding2666]

Yes the code / auth token you get from Spotify does expire every 60 minutes or so. That is why you have to use the refresh token to get a new token when it does expire.

[@azerty-by4yh]

Could you give us a hint on how to write the spotify link onto the NFC tags. I'm currently using an app on my Android but it seems to corrupt my card

[@dhruvajindal4932]

How do you program esp32 with VS Code. Isn't the Arduino IDE the only which is supported?

[@makeratplaycoding2666]

You can use VS Code, but it still requires the Arduino tools to be installed. I enjoy it a lot more than using the Arduino IDE. Here is a link to how to setup VS Code for Arduino learn.sparkfun.com/tutorials/efficient-arduino-programming-with-arduino-cli-and-visual-studio-code There are lots other help on the web too if you search for 'use visual studio code for Arduino'

[@dhruvajindal4932]

@@makeratplaycoding2666 Thanks :)

[@robertschumacher9640]

Did someone get it up and running? I tried it with an ESP8266 i had lying around. I have no experience with programming an ESP. However, my approach seems to be correct. First I downloaded Arduino IDE, adjusted the Seetings.h file with my values and loaded the board software of an ESP2866 into IDE. Then I added the .ino file and in the Library Management I added the WiFi.h and the rest of the .h files from the folder. Unfortunately, I get a error message in IDE afterwards

[@robertschumacher9640]

EDIT: I did not connect the RFID Reader. Could this be a part of the problem

can I use an ESP8266 for this project?

You should be able too as long as you have enough IO Pins.

I am going to take that as a compliment. 😀

All your talk of nerds using a "real IDE like VS Code", and not one person has dropped an elitist, snide comment about VIM? *sigh*. "Pfft. VS Code is a REAL nerd IDE? I only use VIM, because a GUI that makes sense with a mouse to click on stuff is for LOSERS". Now your comment section is complete...and I hate myself a little...

Yes, I agree VIM takes you to a higher level of nerdism. 😂
