 | | Too many sensors
|
|
I received a package from Lego yesterday. It contained gears, a motor, and two rotation sensors. Now I'm stuck trying to figure out how to use all five sensors at once, 1 light, 2 touch, 2 rotation. I know how to combine a light with a touch, but (...) (25 years ago, 8-Feb-00, to lugnet.robotics.rcx.legos)

the LNP stuff is neat, but it seem's that the remote control isn't using either "integrity" or "addressing" protocol how do I access directly the incoming IR buffer ??
