Some things to do with pressure sensors Answered

Two projects I'm thinking of will use pressure sensors.

The first is a device that would sit under coffee air pots.  There have been countless times when I've gone to get coffee at a self-serve place and there are five pots, but no one tells the counter person they are running dry and I then I have to wait for them to brew.  A pressure plate under the pots would control set of red/yellow/green LEDs to indicate how full the pots are.

The second is to use a pressure plate outside the door where your pet comes in and out of the house.  It would trigger a doorbell when your pet wants in before it gets a chance to start scratching up the woodwork.
