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 Due Board – 32-bit Microcontroller for Advanced Arduino Projects from Circuitrocks is ideal for DIY electronics builds.
Great for Arduino, ESP32, Raspberry Pi, and robotics or school projects here in the Philippines.
Arduino Due is the original 32-bit powerhouse in the Arduino lineup—built on the Atmel SAM3X8E (Arm® Cortex®-M3) running at 84 MHz. With 54 digital I/O, 12 PWM, 12 analog inputs (12-bit), and two 12-bit DAC outputs, it excels at fast control, data acquisition, and audio-capable projects. The Due keeps the familiar Mega footprint, adds **dual micro-USB ports** (native & programming), and uses **3.3 V logic** for modern peripherals—great for labs, robots, and embedded prototypes in the Philippines.
