1. Control of two stepper motors

Throughout this process, I’ve been using the very helpful ‘is my blog working‘ tester to check delivery / processing times. It’s interesting to check this site against others […]

one of the important upgrades from the proto-type is to change the old keypad, the knocked-up version described in this post, to a proper ‘matrix keypad’ (ie with numbered buttons) as seen on the right …
