The photosensitive resistor can detect the strength of the outside light. The stronger the outside light, the smaller the resistance. When red LED light is projected on a white area and a black area, the photosensitive resistance is different due to the different reflection rate, which is convenient for controlling subsequent circuits. LM393 is a dual-channel voltage comparator integrated circuit consisting of two independent precision voltage comparators. It is used to compare two input voltages and change the output voltage according to the input voltage. The custom-made motor has a reduction gear and greatly reduces the difficulty, which is very suitable for use. LM393 compares two photosensitive resistors and stops one side's motor if the resistance has an imbalance. The other side's engine spins faster to bring the car back in the right direction. The entire process is a closed-loop control system, so it can be controlled quickly and sensitively. Assembly instructions: Step 1: Welding circuit The electric welding part is simpler, the welding order follows the principle of component level from low to high, the first eight welding resistors. It is important to use a multimeter to confirm the resistance is correct. Step 2: Mechanical Assembly. The red wire is connected to the positive 3V power supply, the yellow wire is grounded, excess wire can be used as a motor wire.
