Hi,
My guess is that the guy wants the 7-segment display to indicate
which of the opening parts is not closed properly.
Bonnet
F.R. door
F.L. door
R.R. door
R.L. door
boot/hatch
sun-roof
Maybe each segment could just refer to one item, with words
round the edge ?
Such an arrangement would require a minimum of electronics,
just the dropper resistors, and the wiring, and the switches
or contacts fitted to each opening part.
Also if two parts weren't closed, they would show accordingly.
I might be quite wrong, maybe he wants numbers for parts not
closed properly, but what about two or more not shut ?
Dunno, just a suggestion.
Regards, John
