About this item

• Function as a Real Doorbell, Ready to Use Right Away：Once soldering is completed, it can serve as a practical home doorbell. It supports tone adjustment and is suitable for various scenarios such as courtyards and bedrooms (a speaker needs to be self - provided).
• A Classic Electronic Teaching Project：Learn core electronic principles such as audio oscillation circuits (NJ5655 chip), capacitor filtering (100μF/103), and diode rectification (IN4148). It is ideal for STEM classrooms and interest - based practical activities.
• Industrial - grade Components for Professional Learning：It includes an NJ5655 audio generator, IN4148 switching diodes, precision resistors, and capacitors, restoring real - world circuit designs and moving beyond toy - level experiments.
• Beginner - friendly Design：The PCB board clearly marks the VCC/GND polarities. The pad sizes are optimized, and it comes with a modular circuit layout, enabling even beginners with no prior experience to easily complete the assembly.
• Dual Value: Learning and Practical Use in One：It serves both as an electronic teaching model to demonstrate the working principles of circuits and can be upgraded into a home security device. It supports the expansion and connection of wireless modules (additional accessories required).
