Smart Robot Car Kits Tracking Car Photosensitive Robot Parts for DIY Electric Toy,Default NO5238

Feature:

Non-programmed smart tracking car kit

After the successful installation, the car can travel along a black track with a width of 15mm.

The circuit consists of several parts, photoelectric sensing, voltage comparison, and motor drive.

The reflectance of the light-emitting tube projected to the black and white portions is different, and the resistance of the received photoresistor changes.

LM393 compares the size of two photo-resistors, controls the operation of the motors on both sides, and corrects the direction of the car to ensure that the car advances along the black track. The motor is equipped with a speed reducer. Do not rotate vigorously to prevent damage.

Note: Powered By 2pcs AA Battery (Not Included)
