Hello
I have been using ThingSpeak for about 2 years with no problems. I am observing sensor data and connecting widgets to some of the values. Since yesterday, there are some of the widgets that send blank values. Have you changed something?
Thank you

Hello, all!
This is my first post after just joining this discussion, so please forgive me and provide kind assistance if I have posted to the wrong subsection!
I have a good interest in learning sql server course and right now I am taking help from various platforms like https://www.coursera.org/ https://www.udemy.com/
Also I have a doubt that is it a good option to learn from platforms like this or I should go for some sql server online training . I have searched for the solution of my queries in various above platforms which helped me up to some extent only as it was not directly given by any expert or trainer.
Hoping in getting a quick response
Thankyou in advance.
Hello, I am a student and I am working on a neural network for a line follower car and I would like you to recommend a tutorial to implement it in simulink.
Hello, I would like to send temperature and humidity data from my ThingSpeak channel to the https://www.wunderground.com/ service. I managed to configure the initial connection through ThingHTTP, and on the WeatherUnderground website, there is information about data updates, but there are no actual values: https://www.wunderground.com/dashboard/pws/IKORON5/table/2023-11-19/2023-11-19/daily
I don't know how to correctly configure all the options in ThingHTTP and in the Apps - React section.
Dear contest participants,
Happy Friday! I am thrilled to share some exciting news with you. Cleve Moler, the father of MATLAB, has just published a captivating blog post dedicated to our outstanding Flipbook Mini Hack contest!
In his blog post, Cleve expresses his genuine admiration for the multitude of creative styles, artistic talents, and ingenious programming techniques that have been showcased throughout the contest. What's even more remarkable is that he handpicked some of his personal favorites! You don't want to miss this opportunity to see what Cleve has to say.
But that's not all! Your exceptional animations have sparked immense interest among the MathWorks teams. This means you have a direct impact on the next generation of animation tools in MATLAB! We value your thoughts and ideas, so please don't hesitate to share them with us.
Let's keep up the phenomenal work in the remaining two weeks, and together, we'll continue to push the boundaries of creativity and innovation.
Wishing you all an incredible weekend ahead!
Enthusiastically yours,
Chen
Dedicated to all Flipbook contest lovers! :D
In just one week, we have about 200 amazing animations! We see many creative and compelling animations and more importantly a lot of FUN!
Now, let the voting begin! Vote on the animations you love. Also, share them with your friends, classmates, or colleagues. Show the world the beauty of mathematics!
Mini Hack Winners - Week 1
You probably can imagine how hard it is to pick the winners, given so many awesome entries there are! We came up with several categories:
Landscape:
Trees:
Illusion:
Cartoon:
MATropolis:
Geometry:
Congratulations to the winners! Each of you won your choice of a T-shirt, a hat, or a coffee mug. We will contact you after the contest ends.
Finally, we encourage all of you to share your experiences, thoughts, and feedback in our new contest discussions channel!
Loving all the animations I'm seeing so far and feeling so inspired and impressed by what y'all are sharing. Thanks for loading me up with new topics to learn about!
The Flipbook contest is currently in full swing! It's been truly inspiring to see the incredible artwork you've all created using MATLAB! Checkout the gallery page if you haven't already.
We have some exciting news for our contestants today! In order to allow for more complex and unique creations, we've increased the MATLAB Evaluation timeout limit from 55 to 235 seconds!! So, don't hold back! Feel free to throw in those extra intricate lines of code without worrying about timeouts.
To all those already participating, we commend your efforts and encourage you to keep pushing your boundaries. And remember, there's always room for more. So, why not invite your friends and fellow MATLAB enthusiasts to join in the fun?
We also encourage everyone to engage in the contest discussions channel. Share your experiences, insights, and feedback about this contest. Your contributions enrich our community and help us improve future contests.
Looking forward to seeing more and more entries in coming weeks!
when I examine the data stream on an arduino ide I get a lot of "stuff" which I dont understand.
1 what does it mean?
2 how do I prevent it?
We reached the 100 animations milestone in less than 3 days! We are thrilled to see so many creative entries and talented members learning from each other.
Note that this contest is not just for experts. People with all skill levels can participate, improve their MATLAB skills, and have fun!
We have created new resources and tips for you to get started.
- Contest introductory video. The 3-minute video provides you with a quick introduction to how the contest works and how to create a simple animation.
- Animations blog post. The post demonstrates some coding techniques that can make your animations easier.
- AI Chat Playground. This is a new community app we just released. You can leverage the Generative AI tool to write initial draft MATLAB code or modify existing one.
- Get ideas from previous Mini Hack contests. There is a large gallery of amazing images, which provide you with ideas and code to start with.
- Remix is highly encouraged. Learning from others is the most effective way to learn. Make some SMALL changes and see what it would look like.
We look forward to seeing more of you joining us and having more fun!
Unlike last year's contest, there are some new technologies this year that might offer some advantages. Namely generative AI's like ChatGPT, Bard, etc. Not to be excluded, MathWorks just launched the AI Chat Playground :)
Hello,
i want to write the power data from my Tasmota IR Device to my channels, but it does not work.
I have created 3 channels and i use the correct write API in the script. I use the following script:
>D
>B
=>sensor53 r
>S
if upsecs%20==0
then
=>WebSend [api.thingspeak.com] /update.json? api_key=xxxxxxxxxxxxxxxx&field1=%sml[1]%&field2=%sml[2]%&field3=%sml[3]%
endif

I get the messages in the console that the data was send but my channels stay empty.
What do i miss ?
Thanks for help
good afternoon everyone my name is Dundu lawan haruna ,i'm a final year student at the department of computer engineering ABU Zaria, Nigerian , and i wanted to do my final year project based on computer vision : project topic , designing an eye glasses to help those people with visual imparement to be able to navigate enviroment efficiently , that's why i need a support from you guys ,all advised are highly well come , thank you for your support.
Participants across all skill levels are welcome to join! You can participate by creating a new animation or remixing an existing one with up to 2,000 characters of MATLAB code.

We look forward to seeing your creative work. Let the contest begin!
I am collecting Data at 1 minute intervals using esp8266, the data is then sent to Thingspeak on the minute intervals. However I would like to store the data collection on the esp Ram. I am using batteries to power the circuits , if I can store the data and send it on demand I can save quite a bit of battery energy (used up by wifi) - (I already use sleep mode between intervals). As well as using Thingspeak to visuliase the data, I also use a third part app called Thingview which 'feeds' off thingspeak. I am looking for a way to trigger the 'data send' upon opening thinkspeak chanel,so rather than sending every minute it might need to be accessed two or three times a day, is this possible?
Thanks Edward
Hi!
I can't see my data in the charts. I'm using arduino wifi and the connection works.
Maybe I did something wrong in this options
Is there a way to get a handle or link to the database each time I do a WRITE or group of WRITEs? I need to access the set of records that comprises a user session, which could be many WRITEs. My impression is that Thingspeak appears as a continuous stream with no way to mark a set of WRITEs as a group or session. Methods I have tried like retrieval (READs) using timestamps and other after-the-fact queries are not very accurate or user friendly. Thanks.
