Hmmmm I think you are right...!! | |
Chuckles, yes that is it! Something simple, but could the ir receivers i.e. these things already built that plug into a serial port do it also?
Of coarse if a photo transistor could do it, then I could tie directly into
the input of a galil card or ethernet i/o unit which could be easier.....
Could a photo transistor pick up a red led on an electronic edge finder from
the corner of a machining center?? |
