Fingerprint Sensor Flashing

I am new to Arduino and I was just wondering wether it is possible to stop the built in led from flashing on a fingerprint sensor. It gets pretty annoying after a while. Is there like a LOW or HIGH command that I could use?
Thanks!

What sensor? Where’s the documentation?

If all else fails you could completely turn the power off to it. Either directly with a pin (if it is low enough power) or with a transistor or a relay.

Of course it then wouldn’t be able to detect a finger until you powered it up again.

ok thank you
