Flex sensor

I'm planning to connect a flex sensor to a Stamp for use in a data glove. I understand the sensor has a maximum resistance: 30k ohms to 40k ohms, proportional to the degree of flexing or bending.

Anyone have a good suggestion on the look of the code for something like this? -Or- any ideas as to where I can find information..

Thanks!

    You could use the RCTIME command.· For a schematic look at the analog photoresistor section of the boe-bot manual (light sensing)· All you have to do is replace the photoresistor with the flex sensor.

    or an ADC·(http://www.parallax.com/Store/Components/IntegratedCircuits/tabid/154/CategoryID/31/List/0/SortField/0/catpageindex/2/Level/a/ProductID/245/Default.aspx)

    It looks like the whole path you took is in there (did you search for "adc" by any chance?)

    ·

    BTW if you use an adc, put a pulldown resistor of a very large value to the pin otherwise you will always get the highest value.

    I think I messed up the color in my previous post. I can read it (I have the black background setting), but when I log off (white background) I can't. Whoops.
