I am looking to gauge some water levels in one of my projects so I got the Miltone eTape from sparkfun: Liquid Level Sensor - 8" - SEN-10221 - SparkFun Electronics
I am trying to interface to it and am having some troubles, does anyone have any advice or sample code?
Have you read the appnotes - http://www.parallax.com/Portals/0/Downloads/docs/prod/sens/eTape_AppNotes.pdf
It is in fact a variable resistor so you can build a voltage divider with it and use code similar to - http://arduino.cc/en/Tutorial/AnalogInput -
How did it go?
I've just got some eTape to do the same thing.
StuHooper/Narwhal: I too have an eTape on the way from Sparkfun. Is there anything I should know about or is it relatively straight forward to interface?
I bought an eTape a few weeks ago, and found some code on this site:
It worked great- it averaged out the readings, and converted to inches.
