Arduino + ESP8266 hacking

This post is quite a deal more technical than my usual fare. I’m doing this as a write-up of some of the learnings, in part to share with participants at the OzBerryPi IoT meetup that occurred last night.

I’ve recently been investing some time into a project using Arduino as a wifi-enabled energy monitor.

I had an hypothesis that open-source hardware such as the Arduino and related chips like the ESP8266 wifi chip were approaching the point where someone like myself, with a reasonable degree of experience in web development, might be able to build a low-cost embedded electronics project (and potentially, down the track, product).

Here are a few key learnings from the journey so far…
