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 500pcs 5mm LED Assortment Kit is a useful LED set for electronics projects, Arduino builds, breadboard testing, school activities, repairs, and DIY circuits. It includes red, yellow, blue, green, and white LEDs packed in a storage box for easy sorting and workbench use.
This kit is ideal for students, hobbyists, makers, and technicians who need assorted 5mm LEDs for indicator lights, signal outputs, lighting tests, display projects, and low-voltage circuit experiments.
This kit includes 500pcs of 5mm LEDs in five colors.
Note: Resistors are not included. Use the correct current-limiting resistor for each LED to help prevent damage.

Always use a proper current-limiting resistor when connecting an LED. Connecting an LED directly to a power source may burn it out.
LED polarity matters. The longer leg is usually positive, while the shorter leg is usually negative. Check the polarity before powering your circuit.
