Hi everyone, sorry for the lack of updates this past week and a bit. I've been recording and editing my 5 minute video. Hopefully I should have this posted this evening. I have drawn up a quick system design diagram for ESPLux. It shows a very high level of each of the components and how they are connected to each other. It is a pretty simple little circuit, so there isn't a great deal to show here. It does however do the job quite nicely! Click on the image to see it full size.

I drew this on draw.io. Pretty neat little site!
