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.

Simple Metronome using transistor

This circuit be Simple Metronome circuit model to be simple. It use the transistor be important equipment by very the circuit is the character Astable Multi vibrator. For produce something the sound beep. By can fine VR1 for get sound tone Generator follow can want. A loudspeaker that use to is supposed to impedance 8 – 32 ohm railing land. For decrease the popularity will down and may lead , output , go to feed reach still the amplifier microphone has changed , capacitors 10 uF. The detail is other , see in the circuit.

Warbling Alarm Circuit with tone Generator

The circuit is see this it , sound generator warbling tone , which hear distinct in swoop down that have a voice disturb , get more than , single tone. By the transistor Tr2-TR3 assemble the circuit tone Generator , Which frequency modulated with output of TR1 which it frequency generator saw tooth sound generator sound signal can fine can decorate with R7 effectively follow want. And still can fine C1 for make which frequency modulated change to with. By a loudspeaker that use to is supposed to impedance 35 ohm railings are if use lower this be supposed to resistors , build serial keep with. For decrease the popularity will down. And may lead output go to feed reach still power amplifier circuit , get change capacitors 4 uF. The detail is other , see in the circuit yes.
