Flip flops circuit

July 3, 2011 by elecfree

555 timer Mono stable (one shot) The two circuits below illustrate using the 555 timer to close a relay for a predetermined amount of time by pressing a momentary N/O push button. The circuit on the left can be used for long time periods where the push button can be pressed and released before…
Monostable Flip Flop The monostable flip flop, sometimes called a ‘one shot’ is used to produce a single pulse each time it is triggered. It can be used to debounce a mechanical switch so that only one rising and one falling edge…
CMOS Toggle Flip Flop Using Push ButtonThe circuit below uses a CMOS dual D flip flop (CD4013) to toggle a relay or other load with a momentary push button. Several push buttons can be wired in parallel to control the relay from multiple locations. A high level from the push…
Bistable Flip Flop Here are two examples of bistable flip flops which can be toggled between states with a single push button. When the button is pressed, the capacitor connected to…
D – Flip-Flop Made With A LM556 TimerThis circuit is a hybrid – D type Flip-Flop that is constructed from an LM556 – Dual Timer integrated circuit. The circuit is essentially a High-Tech and overly expensive…
Multipurpose Flip-Flop Timer This particular timing circuit can be used to time one-shot events from a few seconds to a few hours. And in standby mode (ie, with RLY1 and LED1 off), its power consumption …
12F675 as a D-type or JK-type flip flop Since I implemented a D type flip flop using the PIC Logic Elements I thought I might go the other way and implement an entire D type flip flop in a single PIC…

Smoke detector circuit May 22, 2013
A smoke detector is part of a sophisticated alarm system. Which within the system is a professional, most will include Section detector gas, room filling ions. Or sensitive to radio signals. However, this circuit does not have to be so complicated. Just another 2 LDRs and LED detection. Only the number of IC LM1801, the circuit helps the device is much less. […]

Fuse status indicators for 12 volts power supply May 21, 2013
This circuit is a Fuse status indicators for power supply 12V. If a fuse is normally, the LED is going to lights all the time. But when it lacks, the LED will be blinking. The value of this equipment in the circuit is suitable for a 12 volt power supply. However able to change the power supply 6 volt or 24 volt, By reducing the value of the resistor to half […]

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 […]
