The Design of Remote Control Car Based On MCU
Abstract
Along with the development of electronic, automation is not a fresh word any more, and no-man controlled cars will be realized. The new invention of modern intelligence, is a future of development, he can follow the pattern set in advance in an environment where automatic operation, no human's management, used in scientific exploration and so on. Smart electric car is one of expression. That system is based on the design of 51 MCU controlled car. 89C51 MCU is eight-figure microcontroller, which receives high praise from the users because of its easy use and versatility. This graduation design introduces how 89C51 b35MCU realize the remote control of the car, a combination of the practical application and design. This system designs for the purpose of the topic request, using 89C51 MCU as control core, the car motor control by L298N,and wireless remote control which chip 吉利豪情1.3PT2262/2272 device, with the electric car, driving, and the particular path park. The whole system of the circuit structure is simple and reliable. This paper introduces the hardware design method of the system and the analysis of the test results.
