(...) There are the Cybermaster touch sensors with resistors, but that's a rather expensive solution. (...) Your idea is both simple and great and I just wonder why nobody thought of it before. So how to get more lights? I just have one from the (...) (24 years ago, 4-Oct-00, to lugnet.robotics)

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 (...) (24 years ago, 4-Oct-00, to lugnet.robotics)

(...) Those resistors in the Cybermaster touch sensors are in parallel to the sensor. You can read its value when the sensor is not pressed. Cybermaster uses it to figure out which sensor is connected to what port before starting the actual program. (...) (24 years ago, 4-Oct-00, to lugnet.robotics)

Hi Rob, (...) Yes. But by looking carefully at the connectors it's not too hard to figure out how to do it. (...) I think it is just that in most cases parallel connections are needed, and you got to decide between the two possibilities if you want (...) (24 years ago, 5-Oct-00, to lugnet.robotics)
