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 classic classroom board, ready to run out of the bag. This micro:bit Go kit bundles the micro:bit V2.2 with a USB cable, battery pack, and batteries - code it in the browser, unplug, and it keeps running on its own.
V2.2 is a minor revision of V2 (internal interface chip change). Every V2 HEX file and editor works the same.
