2WD Smart Robot Car Chassis Kit

D2-1 2WD Smart Robot Car Chassis Kit DIY For Tracking /Line Following Soldering Project – Photoconductive Resistance Component: It can detect the intensity of external light.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 Comparator Integrated Circuit: it consists of two independent precision voltage comparators. Its role is to compare the two input voltage based on input/output voltage level. It control the motor’ s operation and correct the direction of the car. – DC Motor Driver with Gear Reduction: It can control the speed of smart robot car to avoid running too fast. – In the process of assembly , we can not only be familiar with the principle of mechanics, but also can gradually learn: photocell, voltage comparator, motor drive circuit and other related electronic information.
