摘　　要：震动开关是一种机械式传感器,常用于检测物体是否因为受到外力而发生倾斜、震动的情况。JK触发器是数字电子技术中用于时序逻辑电路设计的经典芯片。在实际生活中,很多群体需要智能的小夜灯来进行照明。文章将时序逻辑电路设计的理论知识应用到解决实际生活问题的电路设计中,阐述了一种基于震动开关及JK触发器的小夜灯电路的设计,通过震动小夜灯来实现开启、关闭夜灯,及切换强、中、弱光挡位。Vibration switch is a kind of mechanical sensor,which is often used to detect whether objects tilt or vibrate due to external force.JK flip-flop is a classic chip used in the design of sequential logic circuit in digital electronic technology.In real life,many groups need intelligent night lights for lighting.In this paper,the theoretical knowledge of time sequence logic is applied to the circuit design of solving practical life problems.The design of a small night light circuit based on the vibration switch and JK flip-flop is described,which can turn on and off the night light by vibrating the night light,and switch between strong,medium and weak light blocks.
