Aueabc Star Shaped LED Breathing Light DIY Soldering Kit, 5-Pointed Star PCB with 20 SMD LEDs, DC4-6V Powered Electronic Assembly Set, Unassembled Components for Beginner Solder Practice & STEM Projects, No AA Batteries Included

• Model: Star Breathing Light Kit; Working Voltage: DC4-6V (powered by 2 AA batteries, NOT included); PCB Dimension: 48×48mm; All through-hole and SMD components design; Package includes bare star-shaped PCB, 20 SMD LEDs, resistors, capacitors, IC chip, battery holder, wires and user manual with soldering guide; NOTE: The kit is sold as unassembled components, requiring manual soldering and assembly by users. It is recommended for those with basic soldering skills.
• This kit is designed for soldering practice, especially for surface-mount device (SMD) components; It includes detailed soldering instructions, such as polarity identification for LEDs, IC pin alignment, and SMD soldering techniques; Perfect for beginners to build confidence and improve precision soldering skills.
• The breathing light circuit is a classic example of basic electronic principles, including oscillation and LED dimming; The kit comes with educational content explaining how breathing lights work in consumer electronics like phones and cars; Great for classroom STEM activities, after-school projects, or family parent-child learning.
• The kit arranges 20 SMD LEDs in a five-pointed star pattern; Controlled by the circuit, the LEDs gradually dim and brighten like breathing; Creates a soft, decorative light effect; Ideal for learning about LED drive circuits and pulse-width modulation (PWM) in a fun, visual way.
• The user manual includes step-by-step assembly instructions, soldering tips, and troubleshooting guides; Components are arranged by height for easy soldering (small parts first, then large ones); Even first-time users can complete the project with careful following of the guide.
