PROJECT SWITCH - Coffee cup for blind people

I was obsessed with using coffee as a my switch, and I planed to make one
for blind people. Basic idea is that it’s really hard for blind people to know how
much water, coffee, or juice they poured into a cup. Since, coffee is hot, it can
be very dangerous for the blinds also.
Thus, my switch detects the coffee level, since coffee is conductive, and makes
alarm sound so blinds can hear! and knows when to stop pouring coffee.
