Hi Juergen, (...) I realize that I am using two lights where I only need one. Its just simplest to connect both lights to one sensor. I think I came up with a scheme to use only one light, but the wiring was somewhat convaluted. (You want the light (...) (25 years ago, 4-Oct-00, to lugnet.robotics)

Here is a shot through the robot's camera. I just added a Lego gauge. The little gauge is fun, but it times out to sleep. It has a lot of functions... a few more might be fun. (URL) (25 years ago, 4-Oct-00, to lugnet.robotics)
