Im simply using two lever arms that "fall" into the touch sensor (...) (22 years ago, 7-May-03, to lugnet.robotics)

| | | | 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 (...) (22 years ago, 8-May-03, to lugnet.robotics)
