You can try setting your sensor mode to raw or percent, and seeing if you can get
useful values. I way able to use a touch sensor as a trinary switch this way. The
full range in raw mode is 0 to 1023. I think my values were around 0-300, 301-900
and 901 to 1023. Mechanically, I had a lever that moved horizontally across the
touch sensor's bump. I used it as the wall-detecting arm in a wall-follower.It
was a handy way of getting close, but not too close, to a wall.

In my case, the far end of the arm would move several centimeters over the range
of motion while the end over the sensor would move in a one or two-stud radius
arc. In your case of directly pressing the sensor you may not be able to achieve
that sensitivity. Then again, maybe you don't need to.

(...) No, they are essentially switches that are either on or off. Though the whole truth is that they are made from conductive rubber, and that they go from off to on over a very small distance. I once measured this by an arrangement that very (...) (21 years ago, 7-May-03, to lugnet.robotics)
