Another observation. It seems that the IN_TYPE_LIGHT_INACTIVE is really not meant to be used with the RCX light sensor. There is very little sensitivity with this setting. The IN_TYPE_REFLECTION setting is much more sensitive. Too bad that we lost (...) (19 years ago, 2-Jan-07, to lugnet.robotics.nxt)

I am not a NXT-G expert. I'm a programmer, so I moved to NBC pretty quickly. It's much easier for me to do things in a language than with graphics (not to mention the programs are 1/10 the size of NXT-G). Good Luck! David (19 years ago, 1-Jan-07, to lugnet.robotics.nxt)
