Features:
- Model: D2-1
- Name: D2-1 Intelligent Tracking Car DIY Kit
- PCB Size: 105 × 72 × 1.6 mm
- Installation Size: 105 × 85 × 46 mm
- Operating Voltage: 3V
- No Programming Required — Purely solder-and-assemble for quick results
How It Works:
The car uses a photoresistor to detect differences in light reflectivity from the track (black vs. white surfaces). Based on sensor input, it controls the motors to follow the black path. A red LED on the PCB activates when black is detected, helping guide the car along its route.
Working Principle:
- Infrared sensors detect line contrast
- Photoresistors sense light intensity
- Motors adjust based on voltage comparator feedback
- No coding needed; logic is hardwired via circuits
Schematic:
Assembly Instructions:
- Circuit Assembly:
- Solder all resistors first (start with the lowest height)
- Observe polarity for capacitors, transistors, LEDs
- Verify orientation for all polarized components
- Mechanical Assembly:
- Mount the universal wheel and battery holder
- Connect motors, install wheels, and attach tires
- Optoelectronic Components:
- Install photoresistors and LEDs approximately 5mm from ground
- Testing & Debugging:
- Insert 2 AA batteries
- Test sensor reactions to light/dark paths
- Reverse motor wiring if car moves in the wrong direction
