I have the 12in Tape Sensor and an Arduino Uno. I'd like to get use this to measure volume in a cup. They gave me a resistor and a little connector for the 4 pins with the sensor, and I have some wire and a Multimeter.
I am really unsure of how to do even this very basic thing. I would like to extend this into a more useful hack, but right now I'm trying to get basic functionality. In this video, it looks like they're literally just connecting two ends to the multimeter and that works. I have 4 pins though.
Where do I begin?
