thanks, basically what i want to do is use a sensitive pressure sensor of some kind to measure whenever something lands on it, and this would then turn on a light. I have looked at peizo electric stuff and as far as i understand although i could be wrong, they only release a signal when there is...
Would it be possible to make a digital scale turn an led on or off instead of showing a display of numbers. So instead of showing the weight, the light would turn on, and when the weight was zero, instead the light would be off. Any help would be great thanks
