Generating a Delayed Pulse Using The 555 Timer

August 2, 2011 by

The circuit below illustrates generating a single positive pulse which is delayed relative to the trigger input time. The circuit is similar to the one above but employs two stages so that both the pulse width…Read more

9 Second LED Timer and Relay Circuit

August 1, 2011 by

This circuit provides a visual 9 second delay using 10 LEDs before closing a 12 volt relay. When the reset switch is closed, the 4017 decade counter will be reset to the 0 count which illuminates the LED driven….Read more

  • 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 […]

  • 10 LED Flashing using CD4017 May 16, 2013
    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. […]

  • Symmetry harmonic oscillator generator May 10, 2013
    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 […]
