This design is based on application of single chip microcomputer intelligent control, implements a through L298N driving a stepper motor system.This design is divided into two modules, one is single chip microcomputer minimum system module, a L298 is used to drive stepper motor module.With single chip microcomputer minimum system can control through the intelligent sensor MQ - 5 receive soot concentration for AD transform for the voltage to control the step motor, And PID algorithm of the stepper motor speed for real-time detection and fine-tuning, reduce turbulence, and the control power.MCU internal transfer protocol of the carrier, to realize intelligent control of the entire circuit.In single chip microcomputer minimum system module, can show the current user to detect soot concentration and the speed of the stepper motor data such as, in the L298 stepper motor module, can carry on the judgment to the data and be able to accurately to the stepper motor electrical signals, and the detected data, and this system is based on 80 c51 as the core control of adaptive smoke lampblack machine control system, is divided into single chip microcomputer minimum system m
