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 Wired Miniature Electret Microphone is a tiny electret condenser capsule with pre-attached wires — ready to solder into your project. At just a few millimeters across, it's one of the smallest ways to add voice/sound input to an Arduino, Raspberry Pi, or embedded system.
| Type | Electret condenser (omnidirectional) |
|---|---|
| Wires | Pre-attached |
| Size | ~6 mm diameter |
