First Practical Example

Well I have been working on my ESP Widget device and finally have a practical application up and running.  Here it is up and running on my test widget...

What it does is rotate the display between consecutive segments of Interstate 45 as it passes through Houston.  For each segment is will display the average speed and the NeoPixel will be changed to a color corresponding to the speed.

It is actually driven by a backend application that scrapes the public traffic site and formats the data for display on the widget.  Perhaps in time I will publish this as an example.
