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 →Arduino Nano Every – Compact ATmega4809 Development Board from Circuitrocks is ideal for DIY electronics builds.
Great for Arduino, ESP32, Raspberry Pi, and robotics or school projects here in the Philippines.
Arduino® Nano Every upgrades the beloved Nano format with a faster ATmega4809 @ 20 MHz, more memory, and the same breadboard-friendly 5 V design. It’s a compact workhorse for classrooms, wearables, sensor hubs, and robotics projects in the Philippines—drop it on a breadboard and start building.
