Tone Generator Control with light using IC 555

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.

Light Dark Detector Alarm by IC 555

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.

Basic Timer Control with NE555

As friends many take an interest the circuit about IC 555 which be integrated highly popular that circuit. I then lead the circuit sets the time be Basic Timer Control with NE555 come to present again. By it basically the base of the circuit sets the time work instruction easily initial. Press S1 for a already moment liberate for initial setting the time (Timing Cycle) Relay encouraged work (Pulled in). Until anniversary completed work. The R1 and C1 control length of while delaied keep. If use the value C1 very the time long ago go up This circuit meets to wasp Logic pulse with sir. Request have fun the circuit sets the time this easily please sir.
