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.
