Practice Soldering Learning Electronics Kit Smart Car Line Project Robot Electronics School Kits DIY Education Kids Followi G5T8 Deskripsi : Accessories Type : Decoder is_customized : Yes Model Number : Intelligent Tracking Car Compatible Brand/Model : None Brand Name : BUDI Origin : Mainland China Car introduction: After successful assembly, the trolley can move forward along the black track with a width of about 15mm. The circuit consists of photoelectric sensing, voltage comparison, and motor drive. The principle is that the reflectivity of the light-emitting tube projected to the black and white parts is different, and the light intensity reflected to the receiving of the photoresistor is different, resulting in a change in the resistance of the photoresistor. LM393 compares the size of the two photoresistors, controls the operation of the motors on both sides, thereby correcting the direction of the car to ensure that the car moves along the black track. Kit parameters: Power supply voltage: 3V (the kit does not contain batteries, you can buy two AA batteries yourself) Board size: 7. 2*10. 5cm Main control chip: LM393 voltage comparator chip, without programming control, LM393 classic application circuit, teaching model Use Reminder: Since many customers have come to ask why only one side of the wheel turns after the trolley is installed, and the LED light on the top side is on, hereby declare that after normal welding and assembly, when it is not on the track, it is normal that only one side of the wheel turns, and the top side on the same side The LED is on, and both LEDs below are on. When walking on the track, the wheels on both sides rotate alternately so that the wiring can be realized. For details, please see the welding production video (to be uploaded).
