Hello, I would like sense motion (speed) only in one direction. I don't need it to be accurate, I just want it to be a cheap solution (homemade).
I googled something about piezoelectric sensing with the help of a normal crystal (or piezo buzzer?).
Does anyone have more details on that?
Can I sense speed with it?
Thanx for hints,
Meereck
