I am trying to make an automated coffee machine using a labview interface as the only user controls (other than changing the filters). The problem is that the user must be able to select the ammount of coffee brewed (by the cup), The problem is that the reservoir and carafe sensor need to return current values to the computer in order to control each stage, and all the sensors on the market are hundreds of dollars.
I can probably do this with a floating arm and variable resistor, but I am running out of time to come up with a conditioning circuit.
Any hints?
