Just a general question.... has anyone had any reliability issues with Piezo Vibration sensors through a Grove Shield? I bought 4 of them from Seeedstudio and two of them seem super flaky. They work for a while then just cut out. Has anyone experienced anything similar?
Also, I am a super newbie to Arduino and have a project in mind that requires measuring impact. Is using the Piezo Vibration sensor the best way forward? The sensors are polarized 0 or 1023 as output... ideally I'd liek to measure the force of the imact as well.
Thanks for your help!
