Thanks..
My next project is to make a current sensor that logs my household consumption in a similar fashion so that I can get graphs and rdata out of it.

How difficult is arduino? My boy has one as an unopened present, and my younger daughter asked for (and got) a soldering kit for her 12th, so wondering whether it's something she might get to grip with, supported by me?

Basically you download the arduino programming environment to a PC and then you plug the Arduino in to the PC with a USB cable and there are lots of sample codes (sketches) which you can load on to it and try.
https://www.arduino.cc/

It is basically C++ language and straight forward.

you have a set up loop which sets up the sketch to open ports and initialise things
Then you have a main loop which actually runs the program.

Arduinos are simple as the electronics runs exactly as you would expect it to work with 5V and 0V powered logic.
They have sockets where you can push link wire to connect to things like buttons and LEDs.

Much easier than raspberry PI where the logic levels are backwards with 0V = 1 and 3.3V = Zero

Arduino is a lot of fun.

Yeah, well, that was a great deal less complicated than I thought. I bought a box of random breadboarding electronics and had a go.

I feel like I've forgotten more about electronics than I even knew though.
