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 →The Raspberry Pi Zero is the classic ultra-compact Raspberry Pi: half the size of a Model A+, affordable enough for experiments, and powerful enough for media playback, GPIO control, and lightweight Linux projects. It works great as a headless computer (SSH + WiFi dongle/USB gadget) or as a tiny “real” desktop when you add the right cables.
