I think the 08m2 is the right choice for me. A kit that doesn't involve soldering is not helpful to me, and I'm only after a few functions, as described above. From the 08m2 description:

"This 8 pin starter pack is configured for 5 input/outputs of which 3 can be analogue/touch inputs. Supplied with the PICAXE-08M2 chip and the AXE021 8 pin proto board. Self assembly kit (requires soldering)."

This process looks good to me, of learning the basics from Picaxe, and getting some practice before miniaturizing to the device that I want.

When your "in development", you will loose two ports.

There should be https://uk.farnell.com/knitter-switch/drs3010/switch-bcd-horiz/dp/1190426 all sorts of these available including ones with shafts.

You can look at the I2C spec for an idea of what it's used for. I2C stands for inter IC communications and it uses 2 bits to implement a serial port.
It's used to expand the I/O of typical microprocessors.

I read Tesla once used 88 MOSFETs, how many are used now? Palo Alto guys would know.

Any 32-bit, 80 MHz RISC microprocessors ?

I took a while because I wasn't sure what I could say. It actually uses 42 IGBTs now.

Now that's good progress... Too bad Tesla dont have our local home grown turbo-laminar copper sponge water cooling made by an electrolytic process to cool 10kWs of heat loss in IGBT's like cucumbers.
