4-in-1 two-player competitive game console DIY kit

This 4-in-1 two-player competitive game console DIY kit is designed for students and electronics enthusiasts as a fun, hands-on training project. Powered by an STC15 microcontroller, it integrates a digital tube scoring system, a dynamic LED light array, and a three-button interactive interface. The kit includes a PCB and a complete set of electronic components; once assembled via soldering, users can switch between four different competitive mini-games. It combines soldering practice and microcontroller theory learning with two-player gaming. A transparent acrylic case is included, allowing for a clear view of the circuit structure after assembly—making it ideal for classroom training or extracurricular hobbyist projects.

Key specifications:

Hardware structure and functionality:

1. Type-C power port: 5V power input compatible with standard Type-C cables; features an independent power switch for easy on/off control.
2. Dual-digit digital tubes (Left & Right Sets): Independent scoring displays for two players, showing real-time match scores and game values.
3. Dynamic LED light array: Features yellow, green, and red LEDs that serve as interactive visual elements; lights move and illuminate dynamically based on game rules, creating rich visual effects.
4. Three-button interactive system
Left button: Controls rightward LED movement, value decrement, and position adjustment.
Center button: Long-press to switch between the 4 game modes; short-press to confirm; supports mode memory.
Right button: Controls leftward LED movement, value increment, and position adjustment.
5. 74HC595 expansion driver: Uses a shift register to expand I/O ports, driving the large array of LEDs and digital tubes while demonstrating serial-to-parallel driving principles.

Key product features:

1. 4-in-1 multi-game modes: Long-press the center button to switch games; supports interactive two-player battles for engaging, fun, and non-monotonous practical training.
2. STC15 microcontroller platform: Ideal for learning microcontroller programming, I/O expansion, dynamic scanning of 7-segment displays, and LED array driving principles.
3. 74HC595 shift register circuit: A classic digital circuit example suitable for digital electronics courses.
4. Three-button human-machine interface: Features a complete input/output system to help users understand key scanning and logical decision-making programming.
5. Transparent acrylic case: Allows the circuit board to remain visible after assembly, offering excellent visual demonstration effects for teaching.
6. Ideal for soldering practice: Includes a wide variety of components, allowing users to practice fundamental skills for both SMD (surface-mount) and THT (through-hole) soldering.
7. Type-C 5V low-voltage power supply: Safe operation with no high-voltage risks, ensuring peace of mind during student training.

Suitable applications:

Electronics interest classes for primary and secondary schools; electrical and electronics training in colleges and vocational schools; introductory microcontroller teaching; DIY soldering practice for electronics enthusiasts; science fair projects; fun circuit experiments; and casual two-player gaming.

Precautions:

1. This product is a DIY kit (unassembled parts), not a finished product. It requires soldering tools such as a soldering iron and solder; users should possess basic soldering skills.
2. The power supply supports only 5V Type-C; do not connect to high-voltage power sources to avoid damaging the circuit board.
3. Pay close attention to component polarity (LEDs, electrolytic capacitors, chips) during soldering; incorrect installation will prevent the circuit from functioning.
