The wired remote machine car, as a branch of remote control machine car also will welcome a new period of its development. In this paper, STC89C52 microcontroller is used as the core device, developing and constituting the hardware system of a wired remote control machine car. The system can control operating mode of the machine car by using the control key and it has a liquid crystal display function, with a good man-machine interface, easy to operate, convenient and simple. System uses a DC motor, special motor driver chip L298N, combined with the phase drive circuit and the programmable timer / counter 8253 etc. to design the DC motor driver module; system use the programmable interface chip 8255 Scalable Parallel I / O port; HD7279-driven 4 × 4 keyboard and the production of 128 × 64 dot matrix LCD display module. Ming form a human-machine dialogue module, which is showing the real-time running machine car. The system can realize real-time remote monitoring for the motion of machine car, providing a good platform for the motion of robot of the board.
