Features LM393 Comparator ICs DC motor with reduction gear This is a photoresistor that detects external light. The smaller the resistance of the external photoresistor, the weaker the external light. When the red LED light casts on the white and black runways, the photoresistors resistance will be noticeable due to the different reflectivities The difference for the follow-up circuit control The LM393 compares two photoresistors. When unbalanced (for example, the side pressure runway black) immediately controls the motor to stop rotating on one side and the motor on the other side accelerates the motor to reorient and return to the correct direction. The whole process is a closed-loop control So fast and sensitive control. You will love your Diy car kit product manual Brief introduction to working principle The LM393 compares two photoresistors. When unbalanced (for example, the side pressure runway black) immediately controls the motor to stop rotating on one side and the motor on the other side accelerates the motor to reorient and return to the correct direction. The whole process is a closed-loop control So fast and sensitive control. In order to simplify the complicated principle, we first control the intelligent tracking car through the digital circuit. During assembly, we can not only be familiar with the mechanical principle, but also gradually learn the relevant electronic knowledge such as photoelectric sensors, voltage comparators and motor driving circuits. Photoresistor Package includes: 1 pcsx Production of electronic technology DIY smart track car kit for D2-5line patrol car parts (we do not include the battery because of the way of transportation, thank you for your understanding!)
