So, does anyone know about USB-C PD protocols?
More info with pics in my GitHub:

For 3-4 years I've used my Smart Phone Charger to protect the battery from overcharging. The phone sends the current battery charge to my Arduino Mini controller which decides whether to charge or stop charging - all well before the 100% mark is reached.
But now I've got a USB-3 PD (Power Delivery) phone that uses adaptive charging rates which would destroy the Arduino Mini in an instant. A redesign is called for. But how to get those sockets wired up? 24 connections on a single USB socket! No way!

The main problem is that the USB-C (PD) protocol requires that not only are the power lines connected, but also the data lines so that the phone can negotiate with the charger what voltage and current it will get.
The voltage can be anything from 5v to 20v with currents ranging from zero to 3A - a maximum of 33W of power that charges up my phone in minutes. Quite a difference from my old, 5v @ 1A phone.
If you know the answers I ask in the video please do let me know!
