Hey :slight_smile: I'm new to the whole arduino world, and was wondering if it's possible to rig an arduino to a small diesel motor to use it as a tachometer? I've looked into it and people say it needs an alternator, which it doesn't have... Thanks :slight_smile:

i believe you could put a piezo in with very little/no issue.
