 | | Can the touch sensor be used as a momentary switch? (without RCX)
|
|
I never bothered picking up a Mindstorms set, as I have enough trouble finding time for more traditional building and I know I wouldn't get good use from the RCX. So I don't have a touch sensor of my own. But I'm wondering if it can be used for (...) (24 years ago, 27-Dec-00, to lugnet.robotics, lugnet.technic)

(...) Yes you can ! It isn't anything else but a momentary switch ! You have to connect your wire to one of the two pins on the right and one of the two pins on the left. (Or connect your wire to the holes of the touch sensor - there are two little (...) (24 years ago, 27-Dec-00, to lugnet.robotics, lugnet.technic)

(...) I've been thinking about this. It would be great to use it as a switch but I haven't found the logic in it yet. I've used some trial and error to try to find the correct wire positioning but I think I'll have to bring out my multimeter and (...) (24 years ago, 27-Dec-00, to lugnet.robotics, lugnet.technic)

(...) I may be wrong, but I opened one of them and don't find any resistor ?!?! Are there perhaps different versions of touch sensors ?? Or is the black contact in the switch the resistor ??

(...) It will work neither with a motor nor with a lamp (I tried that). The switch is made from conductive rubber whose resistance is too high (several hundred ohms). Jürgen (24 years ago, 27-Dec-00, to lugnet.robotics, lugnet.technic)
