Best practices for Spark Variable update frequency?

Hi @JL_678

Have you seen my tutorial on Spark functions and variables here?

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. That…

Using a very simple reload window interval of 1 second, I was able to get real-time control over a servo with a web page. You couldn't fly a helicopter with this but you could make a lot of control systems work just fine.

You could update the temperature every 10 seconds and other sensors every second and still combine the data into one string to send back to the web.
