Buzzer driver circuit

April 23, 2012 by

็Here is a Buzzer or beep driver circuit, with the small speakers or tweeters pierce associates. There are several circuits as follows.
Buzzer driver circuit
Door buzzer sound with CD4001 CD4060

ew
The Door buzzer sound circuit was two-tone sound. With the switch S1. working of circuit,The IC1 is a frequency dividing circuit, and generator a sound frequency came out.by the C1, R1 are the frequency generator. This audio signal from pin 7 and pin 4 into the pin 1 and pin 8 of the IC2a, IC2c [...]

Peal from the transistor

Peal from the transistor The work of the circuit,which the Tone audio generatorcircuit will distribute to is 2 part, be first part is will the part frequency generator modern by using transistor 2 pcs. build be frequency generator circuit astable multi vibrator which Q1 and Q2 work alternate. When Q1 work LED1 stick lay part C2 begin charge with [...]

UM66T IC MELODY INTEGRATED CIRCUIT

In the circuit basically usability base IC UM66T use sound of music sweet-sounding origin and be usable easily. It use just integrated one circuit and a loudspeaker , piezo buzzer , the small-sized , and have power supply 3V only. The detail is other of integrated number this circuit. The UM66T series are CMOS LSI [...]

  • Logic probe tester circuit May 17, 2013
    They are digital logic probe circuits that you make easliy. Most digital circuits that used CMOS ICs. because I like using CMOS ICs. Because it needs a voltage of approximately 3V to 12V and the power consumption is low. If we use the battery power for longer than IC-TTL. But when problems need to Logic. We use a CMOS IC is suitable or more efficient. And in […]

  • Random Number Generator by IC 4017 and 4011 May 16, 2013
    This be Random Number Generator Circuit there is the character is 10 LED Flasher by use IC 4017 and IC 4011 integrated circuit. For the 4017 IC is a 16-pin CMOS decade counter. It takes clock pulses from the clock input, and makes one of the ten outputs come on in sequence each time a clock pulse arrives. Usability press S1 forLED Flasherrespectively. By pre […]

  • LED Chaser by IC 4017 + IC 555 May 16, 2013
    I believes in that extremely amateur electronics many you, may ever build the LED flasher or light blinks or the LED Chaser prevent come to already. Today I begs for to advise the circuit LED Chaser, by have LED show 10 amounts together. blink stick bright chase go to continually. By have IC CD4017 circuits precede at drive a tube LED all. Which its work be […]

    This the circuit light led flashing with show of 10 LED. By use integrated number circuit CD4017 perform be Decade Counter/Divider with 10 Decoded Outputs. Which it is integrated digital circuit CMOS then use the power supply about 9VDC. For a signal input continue the circuit can produce general frequency may use IC NE555 all right. […]

    This circuit is simple harmonic oscillator generator that easy because use three transistors as main components that In this modern era, look old-fashioned, but if you have a device in hand, should be created be used. Highlights of this circuit, not in use of the third harmonic of the crystal or is a symmetric. But the tuning because the frequency generator […]
