ABSTRACT
This design is:Automatically go back and forth a dynamoelectric small autocar, the adoption AT89 S51 unipole slab machine to control precession, countermarch and limit of small autocar soon, the chip approval figures tube can also display to go back and forth of the number of times in time and process black wire . May also demonstrate that the travel the d
老爷车istance, using the sensor examines whether to arrive at the regulating area, is using monolithic integrated circuit's pwm to modulate velocity, this design does not need wireless and the wired remote control control, through the software control, travels between the compact car is automatically completely the tendency which the future will develop, the environmental protection is also safe, satisfies social the development.
