D2-1 Intelligent Tracking Line Smart Car Kit TT Motor Electronic DIY Kit Smart Patrol Automobile Parts
1. After successful installation, the trolley can move along the black track with a width of about 15mm.
2. The circuit consists of photoelectric sensing, voltage comparison and motor drive.
3. The photoluminescence resistance of the photoluminescence resistor will change when it is projected to black and white parts with different reflectivity.
4. LM393 compares the size of two photosensitive resistors, controls the operation of the two sides of the motor, so as to correct the direction of the trolley and ensure that the car moves along the black track.
5. The motor is equipped with a speed reduction device. Do not rotate vigorously with your hands to prevent damage.
Power: two AA batteries (not included)
Installation size: 105x85x46mm/4.13×3.34×1.81''
Please allow 1-3mm differs due to manual measurement.
