摘　　要：利用Arduino和乐高积木测量了倾斜轨道上的钢球滚动和单摆运动。利用乐高积木搭建了倾斜轨道和单摆装置,利用光敏电阻与Arduino连接,测量了钢球滚动和单摆的运动时间数据,从而测量得到其运动加速度或者运动周期,实验测量值与理论符合良好,表明了Arduino用于物理实验测量的可行性。The rolling motion of a ball on an inclined track and the simple pendulum movement were measured using Arduino and Lego bricks.The inclined track and the simple pendulum setup were built with Lego bricks. Utilizing four photoresistors（ one photoresistor）connected to an Arduino board, the time data of the rolling motion（ the simple pendulum movement）was obtained in order to measure the acceleration （the period）.The experimental values agree well with the theories, which illustrates the feasibility of using Arduino for physics experiment.
