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 BBC micro:bit Go is the easiest way to start learning coding and digital making—now using the micro:bit V2.2 board revision. You get the micro:bit plus the essentials to power it and start programming right away. Perfect for students, makers, classrooms, and quick prototyping.
Code on a laptop/tablet/phone, upload once, then run anywhere using the included battery pack—great for demos and classroom activities.
