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, cutoff  目 录 引言 ························································1 1 光控灯···················································2 1.1 光控灯的原理 ·····················································2 1.2 实际电路 ·························································2 1.3 光控灯的实现 ·····················································3 1.4 光控灯总结 ·······················································4 2 声控灯 ···················································5 2.1 声控灯的原理 ………………………………………………………………………5 2.1.1实际电路 ……………………………………………………………………………5 2.1.2光控电路 ……………………………………………………………………………6 2.1.3声控电路 ……………………………………………………………………………6 2.1.4逻辑电平翻转及触发电路 …………………………………………………………7 2.1.5延时电路 ……………………………………………………………………………7 2.2 声控灯的实现 ………………………………………………………………………8 2.3 电路调试 ………………………………………………………………
