This program turns on motor A and leaves it running until a touch sensor attached to input 1 is pressed, then it turns off the motor and plays a sound: task main() { On(OUT_A); until(SENSOR_1 == 1); Off(OUT_A); PlaySound(SOUND_UP); } Dave (...)

Hi Chris, (...) this is a bit crazy, unless your sensor value is a bit pattern. (...) This is sensible, but are you sure it's ok to use equality and not inequalities like SensorValueRaw(1) < 240?

I've sort of solved my problem, but not in a way which really makes total sense. Both of the below fragments work as expectd: #1 if ((SensorValueRaw(1) & SensorValueRaw(0)) != 255) #2 if ((SensorValueRaw(1) != 255) || (SensorValueRaw(0) != 255)) (...)

All, I'm feeling pretty stupid right about now. I've read the NQC docs, looked in the newsgroups, books, etc, but I can't seem to figure out how to read the touch sensors on my Scout.

Hi Richard, No, NQC does not implement any of the trig functions. However, you can do it yourself. The idea is to use a second order polynomial to approximate the sine function. You can get pretty good accuracy (within about 5%) if you break up the (...) (23 years ago, 12-Dec-01, to lugnet.robotics.rcx.nqc)
