Günstige D2-1 Smart Robot Car Bausätze, Tracking-Auto, lichtempfindliche Roboter-Bausätze, Teile für DIY-Elektro-Spielzeug, ohne Batterie
Kit parameters: Power supply voltage: 3V (standard battery set, you can purchase two AA batteries by yourself) Board size: 7.2*10.5cm Main control chip: LM393 voltage comparator chip, no programming control required, LM393 classic application circuit. Car introduction: After successful assembly, the car can move along the black voltage of about 15mm wide. The circuit consists of photoelectric sensing, voltage comparison, and motor drive parts. The principle is that the reflectivity of the black and white parts of the luminous tube is different, and the intensity of the light reflected to the photoresistor receiving surface is different, causing the resistance value of the photoresistor to change. LM393 compares the size of the two photoresistors and controls the operation of the grading motor, thereby modifying the direction of the car and ensuring that the car moves along the black track. The emotions of smart cars also involve mechanical structure, electronic foundation, sensor principles, automatic control and even microcontroller programming. Electronic participants improve their ability to solve practical problems through hands-on skills. Moreover, smart cars are still a hardware foundation. Just add some control circuits. Yes, it can complete tracking cars, fire-fighting robots, football robots, obstacle avoidance robots, remote control cars, etc.
