Circuit Generator with light
These
circuits is used to control audio with light. In simple transduction And the change of light. To control the tone.,we is recommended that three circuits, each circuits consists of a simple device. Suitable for studying the performance of optical sensors is LDR.
This the Tone Generator circuit that 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.
Today we come to see the circuit detects the light by have a voice warn. When meet the light or be become dark depend on using S1 ( follow the circuit ). For this my circuit uses the integrated circuit IC 555 be pillar equipment again.
You can choose can use many the number be LM555 or NE555 or use the number instead of eat the low beam be IC 7555 all right. For that circuit when S1 stay in a position . And there is the light shines at LDR (
Photoresistor) a loudspeaker will utter. When S1 stay in a position and have no the light at LDR loudspeaker utter also. This easy good circuit friends may have fun IC 555 detector light this please sir.
