Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →Connect this to that without soldering using these quick terminal blocks. They allow connecting of two sets of four wires together using just a flat-head screwdriver. These are UL rated to carry up to 15 Amps, so they're great for high current LED strips! Can be used with wires from 14AWG to 22 AWG
