That is easy -- a micro switch ... now how do you tell if the ROLL is
almost empty ?
This one *is* easy: the holder must be spring-loaded. As the amount of
paper on the roll decreases, and the roll becomes lighter, the roll and
holder will be pulled toward the spring, eventually closing a micro switch
;>)

If you notice the above design is for the 'Seat' not for flushing. For
flushing
you have a volume sensor with the seat. A sound sensor could be handy
for the FAN. :)
I guess I will have to buy blue 'hello kitty' bathroom paper and have a
sensor for the
white tube. Now a NEW windows machine seems to be perfect for this
job... no wait that is computer to handle shitty jobs not a shitty job
of a computer. :)

C'mon, folks. I wasn't going to respond to this thread, but we've had
unattended automatic-flush devices for years. IR, I believe. Walk past it,
no response. Stand (or sit, as the case may be) for more than X seconds and
the device is armed. Y seconds after vacating the space, and you hear the
magic sounds...
No need to waste IO pins on something like that when they're better used
elsewhere.

We had mechanical edge-triggered devices in the 14th century (seriously,
I've admired one for a considerable time). Surely it's not beyond
engineers today to design a device that triggers on the microswitch
returning to 'normal'.
If you were ingenious you'd use 2 microswitches. One to detect the
position of the seat, one to detect somebody sitting on it. A 'rising'
edge on the second (so called, because it detects the person rising ;-)),
not closely followed by the first going to 'seat up' state will trigger a
flush. Lowering the seat, though, might well trigger also trigger a flush.
And we could combine the hand-washing detector with the seat-up sensor,
and then moan at people who leave the seat up ;-)...
