Hi all, recently purchased a spark core and need help understanding how to use accelerometers and piezo sensors in my university project.
developing an electronic device that will record the amount of ‘keep ups’ while playing with a soccer ball, without it hitting the ground (i.e. seeing how many keep ups you can get in a row without it hitting the ground, upon which it would reset).
i was intending on using the accelerometer (adxl345) to recognise when the ball is on the ground and when it is not. when it is on the ground the piezo will not count impacts. Can i create a limit switch out of the accelerometer, whereby the piezo will only count impacts within a range set by the accelerometer? if not, any ideas that would be worth considering?
i am a beginner with all things electronics so forgive me for any misunderstandings.
