A tutorial on how to make a flashing / Blinking / Pulsing LED lights circuit using IC 555 Timer on a Breadboard. In this project the NE555 IC works in astable mode. This circuit can be converted into a flashing LED circuit by using a capacitor across the LED.
Explanation of the working of this LED flasher circuit is at the end of the video. For more 555 timer projects, visit this channel.
The components you need are:
* 555 Timer IC
* Breadboard
* Power supply: 5v-12v
* LED
* Resistors: 100kohms, 470kohms, 270ohms
* Capacitor: 1uf
* Breadboard Connectors
For circuit diagram / Schematic, visit this page: elonics.org/flashing-led-circ...
About 555 Timer IC:
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, function as an oscillator, and as a flip-flop element.

Thank you for your excellent tutorial video! I followed along with the video and was able to produce a functioning circuit. Even better, with the links provided in the description, I was able to tailor the blinking rate to my particular needs. Best electronic tutorial hands down.

@Sa-Thani-Lanna 2 года назад

This is a very good and simple tutorial where I built a system specific to my needs and made little adjustments just as it was explained. Thanks.

This is the best explanation ever. You've explained it best. Thanks a lot. God bless you.

Brilliant. I am totally new to electronics and I am starting late on in life. At 45 years old with disability and poor health. I have just recieved a breadboard kit and this video is so simple to understand that I can follow it. Thank you. Ken, near Wigan UK.

@jlucasound 4 года назад

I knew capacitors in parallel increase the capacitance, I knew resistors in parallel reduces the resistance. You just made me understand how that affects the LED flash rate with the 555. Thank you sir! Subbed. Be safe, good man. 5/9/20.

@hoofbags 6 лет назад

This was gr8! For some reason or other, I often have problems with getting these 555s going, but using your circuit, I got the thing working 1st time. Your presented schematic is very clear and easily understood. Another issue is the mark space ratio, the amount of time the output goes high, in relation to it going low. I'd like to know how to improve this to make it 50% - 50%. Another issue I found is, if you've an FM radio nearby, it will stop receiving but instead will give out a broad band RF signal, which swamps the nearby radio, giving out a loud 'rushing' noise. This can be corrected by a 0.01mfd capacitor connected between pin 5 and ground (negative), I have found. It may not be a problem if working from a battery, though. Thank you for uploading. (o:

Thanks for this video. What values of Ra, Rb and C - and anything else but using the same 6V power source - do I need if I want the LED to be on for about 0.3s and off for about 3s? I could not use the equations to work them out!

Nice! I'm a beginner, I have the circuit built, now I was wondering if there's a way I could make the high and low values differ from each other, I need the high time to be around 500ms and the low time to be around 2sec. Is that possible?

Great video. Very informative. I want to make one for using in my car with 12v volt input to the circuit. In addition to that as led I want to connect it to a particular led within the cluster. The led in that circuit requires 12v to lit it properly. What changes do I need to make in your circuit to fit my requirements. Will appreciate your help.

@zacharydunn4386 2 года назад

Could you replace Ra or Rb with a potentiometer and be able to dial in a specific flash time?

@PerrynBecky 2 года назад

This is close to what I have been trying to find to make a flashing LED for a lighthouse I want to build. I would like it if I could get it to fade in and out though so it would simulate the "rotation" of a beacon. Any help would be appreciated.

@fernandogalvez5219 4 года назад

Great job about the explanation, but there is a curiosity that I have. Where does the number 0.69 comes from because in the video you do not mention much about the number 0.69? Would you mind help me with my question?

@blinky23456 6 лет назад

my friend, what would my resistor values need to be for a 3.3V power supply running an LED rated at 3.3-3.8V @ 20mA?

@sameer248 5 лет назад

If using the 12 volt LEDs can we skip the RL when power supply is 12v?

@servicemi5912 6 лет назад

Hi! I've been finding a circuit to build a led strobe. I just want the led to flash say 5 times in a second and then delay of say 1 second and repeat this cycle again. Please help me Thanks.

@gawoofj3242 6 лет назад

Hi. This is a fun little circuit. Is it possible to have a longer LOW time and a shorter HIGH time. That is some way to wire it so HIGH was 0.69(Rb)xC and LOW was 0.69(Rb+Ra)xC? Thanks for the content!

@MrKetan112 5 лет назад

I need to run four 5mm leds On 5v supply, what changes do i have to make. leds need to blink fast, i need this for my bicycle. Please reply.

@weihaochin7544 3 года назад

Sir, is it possible to get when IC555 output is high all the LEDs remain 'OFF' and when the IC 555 output is low LEDs remains 'ON.'?

@neetapatel9032 7 лет назад

Nice diagram and good vidio and elplaction i like your all vidio nice vidioes make some new vidio ok i like your vidio and all the circuit are working .

@shankarsharma3872 7 лет назад

hi bro...I have done the exact connections with the same reisiter n capacitor values as you have shown in the video.. but my led doesn't blink. it stays on ....I also tried replacing ne555 timer with a new one thinking it may be got fused .but no change..it doesn't blink. just stays on... please say wat needs to be done..

@mskallviedeos7620 2 года назад

Dear I have Tricolour LED Railway torch.It is not blinking. If we on the power button of Red LED It continously Working without blinking. Which component should I replace in that circuit? . Shall I use 470 uf 16 v capacitor instead of 1uf capacitor with all the component as shown in the video?
