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 KY-016 RGB Full Color LED Module is a versatile lighting module that features a 5 mm common-cathode RGB LED capable of producing up to 16.7 million colors by mixing red, green, and blue light. Each color channel can be independently controlled using Pulse Width Modulation (PWM), allowing users to create a wide variety of colors, lighting effects, and smooth transitions. The module includes built-in current-limiting resistors, enabling direct connection to compatible microcontroller boards without requiring additional external resistors.
Operating on 3.3V to 5V DC, the KY-016 is compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontroller platforms. Its simple interface and compact design make it ideal for LED displays, decorative lighting, status indicators, and educational electronics projects.
