光控音频发生器NE555

这是音频发生器电路，有趣的，因为可以控制声音与光线。通过使用集成电路NE555的支柱设备，执行模型非稳态多振动器或脉冲发生器产生的声音频率。使用25欧姆小型扬声器。对于设备检测光。我使用LDR，因为可以使用好易和节约。对于音声的使用，可以处以罚款C1。许多价值，使低沉的声音，但是当值是有点让高大的声音上升。其他的细节，看到更好的电路。

This theTone Generator circuitthat interesting because of can control the sound has with the light. By use the integrated circuit NE555 be pillar equipment , which perform produce sound frequency in model Astable Multi vibrator or pulse generator. And use 25 ohm small-sized loudspeakers. For the equipment detects the light. I uses LDR because of be usable good easy and economize with. For tone sound use can fine C1 get. by many values , make the low voice but when the value is a little make tall sound goes up. The detail is other see in the circuit better
