摘要
本次竞赛设计的电动车跷跷板采用STC12C2052AD单片机作为控制核心,控制电机驱动芯片L293D驱动电动小车进行前进、倒退、转向,利用红外接收、发射二极管做成的传感器,使小车按照指示路线行走,并通过重锤检测控制电动车的运动来保持跷跷板的平衡。
The design of the electric car race seesaw used STC12C2052AD as a core control to drive control chip L293D to make the electric car drive forward and regressive. Using infrared receiver made by firing the diode sensor,we directed the car follow the instructed routes,and maintain the seesaw balance through heavy hammer detecting and controlling the movement of electric cars.
