2、trol lamp play an important role in our daily life(like in corridor,toilet,alleyway and so on).They make our life more covenient.By use of them,we can not only protect ourselves from the hurt that maybe caused in looking for the switches of lights in the dark,but also eliminate the phenomenon that s

3、omeone turn on the light but nobody turn off to avoid the waste of resources. It introduces the principle of how to use dynatrons and a nand gate chip to achieve the purpose that control the lights by light and sound,and specially stresses the ways and concrete details about how to use them to achieve the purpose and the solutions of the problems that will be met in the process of making it. Key words: Optically controlled, acoustic control, mircphone, light dependent resistor breakover,
