Alex, Many thanks! Your improved code has been chugging along nicely; probably 100 cycles with no mysteries! Walt White (22 years ago, 26-Dec-03, to lugnet.robotics)

(...) I suspect you're having problems with indeterminate values in the whichPosition variable. This might happen due to the SensorListener getting called in the middle of one of the tests for your while loops... or it might have some other cause. (...) (22 years ago, 26-Dec-03, to lugnet.robotics)

(...) When you say it "misses a command", do you mean that you don't get the touch sensor pressed once in a while? Or the motor doesn't turn when you want it to? If it is the touch sensor issue, maybe the round brick+boat plate that are not close (...) (22 years ago, 26-Dec-03, to lugnet.robotics)

If I shine a bright light into the light sensor it gets to 60 sometimes, but if I put the light sensor very close to a lamp, it gets to 100. I could never get a value lower than 25. "Michael Gasperi" <gasperi@alynk.com> wrote in the message (...) (22 years ago, 25-Dec-03, to lugnet.robotics.rcx)

(...) Are you sure your multimeter is up to the task? I have measured numerous touch sensors (from 1.5, 2.0 and cybermaster), all of them have a high value when not pressed (open for RIS 1.5 and 2.0, 10 to 15KOhm for Cybermaster that have a (...) (22 years ago, 23-Dec-03, to lugnet.robotics)

(...) The touch sensors that come in the RIS set already work as you describe, and are even about the size of a 2x3 brick. The touch sensor has a variable resistance that changes as more force is applied to the button. You just have to read the raw (...) (22 years ago, 22-Dec-03, to lugnet.robotics)
