Form for "control LEDs over the 'net" example

[dcdenison]

Hi, I’m a newbie working through the Electron examples. They are fantastic.

Right now I’m on the “control LEDs over the 'net” example. Works great!

The html form that pushes the LED on/off works perfectly.

Then the doc says, “You’ll get some info back after you submit the page that gives the status of your device and lets you know that it was indeed able to post to the URL. If you want to go back, just click “back” on your browser.”

Is there a way to get that response in another html form?

I’d also like to do that with some of the other API examples, for example the “read the sensor” example.

If I send the info in an html form, it would be cools to get it back in an html form.

Any advice?

Thank you for a great product, and super documentation.

Tutorial: Spark Variable and Function on One Web Page

Let's say you have a Spark core with both a Spark variable and a Spark function. In my case, I have the world's simplest servo control sketch, using the nice miniature servo in the Spark Maker Kit. Using these parts, we will build a servo that you can control from a web page anywhere and monitor the position of the servo too! Here's a preview of the finished tutorial: [image] There is a coarse adjust slider, two fine adjust buttons, and the current position of the servo is displayed. T…

This looks really promising. Thanks!

Still trying to figure out how to display the results from a API push and get inside a web page. I guess it’s AJAX related, but any help appreciated.

Hi @dcdenison

If by API push you mean a publish event, then there are tutorials for that too:

Tutorial: Getting Started with Spark.publish()

Here’s a tutorial to get you started using Spark.publish(). Let’s imagine you want to monitor your core’s uptime, that is, how many hours, minutes, and seconds since the last time the core was reset or powered-up and view it on a web page that you can leave open all the time. You can use the millis() function to measure time and for this example, you can ignore the fact that it can wrap-around back to zero after many days. So you need two things, code for your Spark core and code for a web page…

Using Spark.publish() with Simple JSON Data

Let’s say you have looked at the Getting Started with Spark.publish() tutorial, but you need to send data that needs more processing once it gets to its destination on the web. You have a lot of choices for the data format, but one simple choice is to use JSON, the JavaScript Object Notation which let you send property names and values in an easy to read and easy parse to format. You may have noticed in fact that the data returned by listening to the event stream from a published event is alr…

Multiple Cores Publishing to One Web Page

This is a mini-tutorial! Let’s say your have sensor farm of Spark cores all publishing their data to the Spark Cloud. You need a way to see all that data in near real-time, all on one dashboard. So, how can you do it? There are lots of ways but here’s a simple one that you can edit and change to meet your needs. First a couple of in action screen shots, first for the event named “Uptime”: [image] And here’s another shot for the event named “Temp”: [image] As you can see, you enter your…
