Mini Parking Lot Kit：This diy kit lets you build a miniature smart parking lot by soldering a PCB and connecting motors, sensors, and other electronic components. Designed to simulate the core logic of a real parking system, it offers a complete hands-on experience of how vehicles enter, park, and exit—just like in an actual automated parking lot.

 

Functions and Features：When a mini car drives up to the entrance, the sensor detects it, turns on the indicator light, and the gate automatically lifts to let the car in. After parking, when the car is ready to leave, the exit sensor picks it up, turns on the light again, and opens the gate so the car can drive out. The electronics kit also lets you switch between automatic and manual gate modes, giving you different ways to learn how parking systems work.

 

Interactive Learning Experience：Equipped with 3 parking spots and 4 mini cars, the system displays real-time parking availability on a digital screen. Once all spots are occupied, the gate remains down and the system emits a warning beep, preventing further entry—just like a real full-capacity parking lot. It's a fun and educational way to learn electronics.

 

STEM Educational Soldering Kit：This solder project features a clearly labeled circuit board to help simplify the soldering process, making it ideal for DIY enthusiasts and students. They gain hands-on experience with sensors, motor control, and circuit design, and solder a realistic miniature parking lot while learning core electronics concepts. Perfect for STEM classes and after-school programs.

 

Step-by-Step Paper Manual Included：The kit comes with a full-color printed instruction manual featuring clear diagrams and detailed steps to guide you through the assembly process with ease. While beginner-friendly, it is recommended that users have a basic understanding of electronics, soldering techniques, and hands-on skills for the best experience.

 

This circuit uses an LM393 comparator to detect IR signals. When a car blocks the beam, the receiver voltage drops. If it falls below the potentiometer reference, the comparator outputs high, lighting the LED and lifting the gate. When unblocked, the LED turns off and the gate resets.
