摘　　要：针对传统测量单摆周期实验中计时不准等不足,设计了利用单片机控制单摆实验来测周期T和重力加速度g,文中详细地介绍了硬件电路和软件设计.To overcome the shortcoming of conventional experiment of measuring the period of simple pendulum, the author uses SCM to measure gravity acceleration and period. The precision of the experiment is improved. This paper describes the design of the hardware and software.
