I'm just a beginner with Arduino and I have to design a hockey kit(so I can't use image tracking) that'll detect everytime a ball has an impact with it.What sensor should I use?Considering:- There will be vibrations from walking, falling etc too- The hockey stick's impacts shouldn't count- There will be different forces of impacts.
Standard field hockey balls are hard spherical balls, made of plastic (sometimes over a cork core), and are usually white, although they can be any colour as long as they contrast with the playing surface. The balls have a diameter of 71.3-74.8 mm (2.81-2.94 in) and a mass of 156-163 g (5.5-5.7 oz).https://en.wikipedia.org/wiki/Field_hockey
It's very unclear what you want to do. The title says "How to detect impacts from a ball on a hockey stick?". OK, makes sense. But then you say "The hockey stick's impacts shouldn't count" and now I am confused.I'd experiment with a piezo disc. These are the same things used for a buzzer but they also output voltage when they are subjected to vibration. They're super cheap and the voltage they output varies with the force.https://www.arduino.cc/en/Tutorial/Knock
PaulAgreed, it wasn't phrased as well as it should've. I have to design a kit, so the impacts of the hockey stick or the kit with stuff other than the ball isn't supposed to run the counter.
