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 LTC3588 Energy Harvester Breakout converts tiny amounts of energy from piezoelectric elements, small solar cells, or other low-power sources into a regulated DC output for powering microcontrollers and sensors. It's designed for self-powered IoT sensors, vibration energy harvesting, and experimental off-grid power systems.
