The TJ-56-636 LED follow spot kit is a fun DIY electronics soldering training kit. The kit consists of individual components and requires self-assembly. It features a 9×9 red LED dot matrix, enabling bidirectional XY-axis movement of the light spot for follow-the-light effects. It supports potentiometer adjustment of movement speed and button switching of light movement modes. The circuit uses classic digital logic chips, making it ideal for electronics soldering practice and hands-on projects for electronics enthusiasts. After soldering, you can visually see the light spot moving back and forth across the matrix, combining learning effectiveness with a powerful lighting demonstration.
Core features:
1. 9×9 Red LED dot matrix: 81 high-brightness red LEDs enable horizontal movement of the light spot along the X-axis and vertical movement along the Y-axis, providing multiple light movement trajectories for a visually striking and intuitive effect.
2. Dual potentiometer speed adjustment: Two adjustable potentiometers allow for independent adjustment of the X-axis and Y-axis light spot movement speed, providing free control over the light’s speed.
3. Function key switching: Onboard function keys allow for one-click switching between multiple light-tracking and flowing animation modes, requiring no program modification; the lighting effects are implemented through hardware logic.
4. Digital combinational logic circuit: Utilizing multiple general-purpose digital integrated circuits, this pure hardware circuit eliminates the need for microcontroller programming, facilitating understanding of digital logic and dot matrix scanning drive principles, making it highly valuable for teaching.
5. Through-hole component design: Large pads and clear silkscreen markings make this beginner-friendly design, facilitating component identification and effectively reducing soldering difficulty, ideal for practicing manual soldering.
