(...) I'm not sure how much time you have, or what resources... but you might be able to do this with a single set.

Each is simply a "Wait for Touch Sensor", followed by "Read Timer" block with the result (...) (14 years ago, 24-Aug-10, to lugnet.robotics.nxt)

I am hoping to build a race timer mechanism using my NXT and 4 touch sensors. Essentially I need it to be similar to a pinewood derby timer.

I had a look and osx is supported in leJOS, but it seems quite cumbersome for a total Java illiterate like me. i'd be happier if i can go the Robolab way. Thanks for the tip though, Andrew! If it comes to that, i'll go for leJOS. R (...) (14 years ago, 12-Aug-10, to lugnet.robotics)
