D2-1 Intelligent Tracking Car Motor Electronic DIY Kit Smart Automobile Parts Robot Car for DIY Electric Toy Without Battery




The working principle diagram of the tracking trolley completes the circuit, and the circuit is composed of a line detecting circuit, a voltage comparison circuit, a driving circuit and an executing circuit. The LM393 is a dual voltage comparison IC consisting of two independent precision voltage comparators. Its role is to compare the two input voltages, according to the level of the two input voltages to change the level of the output voltage


The output has two states: close to open or want to pull down to low level, LM393 uses open collector output, so it must be added with pull-up resistor to output high level. The LM393 compares the size of two photo resistors at any time to achieve control. The light from the high-brightness LED is illuminated on the runway. When it is illuminated on white, the reflection is strong. At this time, the photoresistor can receive strong reflected light, and the resistance value is low. When it is illuminated on black paper, the reflection The light is weaker and the resistance value is higher. The tracking car works according to this principle as track recognition.
