Hello everyone. I am planning out a new project. I want to make a circuit that will check for 2 staples on a book as it is traveling along a chain. We have issues on a couple of older stitching (stapling) machines at work when people working on the back don`t see when a staple is missing. Newer machines have something to check for them. I think the newer machines use a hall effect sensor to check for staples, does that sound feasible? reading up on the sensors, you can put a magnet behind the sensor which makes the staple change the magnetic field so the sensor can see it. Is that correct? would that be with most sensors do you think? Or would I have to buy a biased hall effect sensor?
The plan is to use some sort of eye to detect the book and then to count pulses till the book passes and then to reset for the next book. Of course a Picaxe would control it all.
