I dont know why my r307 fingerprint sensor not lighting up…when i connect it to pc it will blink for a second and stops blinking…anyone have troubleshooting ideas…i done everything i can from tutorials

It’s probably either an error in the wiring or in the software, both you’re hiding from us, so it’s up to you to debug further.

PS: Links to the exact hardware you’re using might help too.
