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 SMD LED 1206 Blue is a small surface-mount light designed for compact electronic circuits. It produces a bright blue light and can serve as a power light, status signal, warning light, or visual display. The 1206 package measures about 3.2 × 1.6 mm, making it suitable for projects with limited board space.
Unlike standard LEDs with long metal legs, this LED mounts directly onto the surface of a printed circuit board. Its flat design helps create clean and compact circuit layouts. It is suitable for both manual soldering and automated circuit board assembly.
This blue SMD LED can be used in control panels, electronic displays, small toys, DIY circuit boards, repair work, and custom lighting projects. It is also useful for Arduino, Raspberry Pi, robotics, and other microcontroller projects that need a small indicator light.
The LED has positive and negative terminals, so correct polarity must be followed during installation. A suitable current-limiting resistor should also be added to help protect the LED from excess current. Check your circuit voltage and required resistor value before powering the LED.
Its small size requires careful handling and accurate soldering. Fine-tip soldering tools, tweezers, and proper lighting are helpful during installation. Avoid applying heat for too long, as excess heat may damage the part.
The listing includes 100 pieces, making it useful for production, repairs, classroom activities, and electronics practice.
