I just copied your circuit on the breadboard and so far I tested an led and pot to threshold on the 555 and it's blinking! Which tells me the timer is working. Other led chaser tutorials on youtube fail to explain the stages and educate at the same time. Many thanks!
Hi Elonics team. As a novice to the world of electronics I have spent many hours trawling through the internet for videos and guidance on creating basic circuits. I would like to commend you all for the work you do and say that without any doubt your tutorials are by far and away the easiest to follow on RUclips. Please do keep them coming. Thank you :)
Thank you so much to all you good folks who share their time and knowledge on these sites. Great work!!!!!!!!!!!!!!!!!!
Just made this circuit on a proto board and positioned the leds to make it go in a circle, thank you for the making this circuit.
You're welcome. And nice decision, circular arrangement looks good than the linear one because of continuity.
Your explanation for the circuit is unique and useful
There are many RUclips videos but none of the guys will explain the working of the circuits. They just blindly tell us how to do, but you're teaching us and we're learning the concept behind...
I'm happy that you're doing this......
Explain well keep it up ....
Do more videos ....
Thank you for motivating :)
Awesome and right to the point. I love it. Thank you for this. Great work!
Hi I love your program. l would like the diagram to the circuit, the three push switches that enables the LED'S to glow
Really a good work today is 3 Feb and on 8 Feb I hve submission of this project I. Searching a good project from 2 days and I got this very useful thanks a lot ☺️
I really love this video and it deserves a like from me. I have been making projects with CD4017 led chasers and now i can design complex circuits with it, thank you! 😊
Excellent job. First time I tried it. It did not work. Decided to change out 4017 and it worked like a charm. Thank you. Good job.
I just love this ckt. finally this ckt is working.. God bless you bro....
Thank you it worked after 2 tries
nice, clear video - thank you!
It works nicely. Thanks!
I made a separate PCBs for chips and for LEDs connected together with ethernet cable. And it works on 3V also (at least with 7 attached LEDs). Just the LEDs are dimmer.
If you use lower value resistors will your leds glow brighter?
Thanks :D I've been looking everywhere. And this works. At first I was using the. Wrong ic, I got it working after buying the right ic.
Welcome :)
Good job mate, really appreciate your time and effort... 👍🏻
Very good explanation. Thanks you very much.
Wow! I remember building that same thing in the 5th grade. Found a Forest M. Mimms book called getting started in electronics at radio shack. I think it's still in publication... Thanks for the flashback dude.
By the way... If you change the capacitance across the 4017 you can make it go from sequential to RANDOM. Try 470 to 47 uf... I forget the pinouts. Back then garage door openers used 10 pin dipp switches to select the code. I used this technique to randomly cycle the codes on a remote. Given a few minutes I could usually open any garage door in my neighborhood. Kids thought that was pretty cool...
Anyway... The correct pinouts are in that old book. If you can find it on amazon. It has really cool circuits in it. The best actually... How I got started. I'm middle aged now... Haha.
That's great! It is considered cool even by today's standards.
well teacher and very simple method of building circuit......
Very good tutorial. Nice job editing. Thanks and subbed
It worked wonderfully thank you
Amazing video's! I have a lot to learn to get my video's to the same level! Great work!
Well explained and clear voice
I was looking for this exactly (for led strip). Thanks.
Simple and effective circuit.
Sir Your explanation is really really awesome...pls make a project about on water level indicator. Thank you.
Great tutorial, thank you

It works, thank you. Keep up the good work.
Sure trickybilly
helpedd us in project
thank you so much
I built circuit, works excellent! thank you
Such a shame I can give only one like, because I feel I should give several. Very clear and well explained video. Keep it up.
Exellant job brother. ..greetings to you from Bahrain. .👍
Thank you for declaration
The project works great, which value off the potentiometer should be replaced in who resistor?
Buen trabajo! Enhorabuena!
Very useful video with nice explanation. Thank you and please share some more .
Sure. You can watch all the videos here: ruclips.net/user/elonics
I felt toooooooooo good bcz I succeeded my first project........ Thanks a lot sir
Excellent video
Very good Video, thank you.
My pleasure
OMG it worked! Thank you very much! I didn't have a capacitor so I substituted a fast flashing led and it worked like a charm! Good instructional!
Hi Sir, Thank you so much I done it is working, Fantastic
ammezing and it's help to learning students
Nice job
Finally it's working
Super one Thnk u
Very good video my friend.
this project is awsome i had made it but please make a video of .how 555 ic timer works
True lecture
Good one bro
This worked perfectly. I just had to add a 5 10K resistors in series to replace the 47K resistor...
which site did you use to simulate this??
super sir thank you
Super bro thanks 💕
While using 555 timer in its astable mode i was able to flash a regular 5mm led with 5 volts. However when i replaced the led to 12 volt one along with 12 volt source there's a constant glow with no signs of flashing. Please suggest a solution.
Ps- having done this small experiment a long time ago i think i may have used a 5 volt 100uF capacitor, which i think i should have replaced with a 12 volt one.
Don't know for sure. Please comment.
Thanks in advance!!!!!
Very good projects

superb
Thanks, we have made the circuit for a project for my son.
We are connecting 3 12v rgb 5050 leds (strip segment) per pin.
This causes a problem at 9 volts.
Only 1 or 2 strips will light, sitting still instead of racing.
However, if I drop the voltage (powered breadboard) to 8v, the circuit works.
The project is to be used on a car for a cub scout event,.
So we are tied to using 9v to power.
Weight and space requires we (3) 3v cr2450 lithium cells in series.
The leds are Continuous Forward Current 3x20 mA, Forward Voltage R:2.0 G:3.2 B:3.2, Peak Forward Current 3x100mA, Reverse Voltage 5V.
The strips include surface mount resistors to be used at 12v.
I am a novice with electronics.
I have tried it with both standard and variable resistor as demonstrated.
So far I have been guessing unsuccessfully what to change to make it work at 9v.
Please can you recommend component values that would enable this to work properly at 9v?
Thank you!
please ignore the request for component values.
It appears the power supply on my breadboard is not reliable and must be running at an odd cycle.
The circuit worked on battery fine, and the version we made on PCB was not completed and had an incorrect connection. It worked once corrected.
It worked as desired with 1 exception - the RGB LEDs when run as white needed a 1.5v source to the positive leads between the 4017 pins and the "white" strips & color correction by adding a pull down resistor on the red lead to provide a balanced output (or the red would draw more power and drown out the blue & green leds).
Thanks
Happy that it worked. Yes, it's easier for the current to flow through red LED's than through green and blue LED's.
You did the right thing by increasing the resistance in series to the red LED.
I really really like your videos
And I'm a 2nd year btech EEE
Superb bro
Any insight on how to modify this circuit to use the trigger source as a piezo crystal?
Its working ❤
Hello sir,can u give us advantages, disadvantages and applications of this project?
Do you have idea how to change cycle time delay?
But same speed chasing
I am using a potentiometer to control and slow down the speed of the 555 and the LM4017 outputs. I'm wanting the LED's to fade when they come on and off and I am experienced with many different circuits that fade LED's. I have tried basic cap and resistor pairings at the LED's and also by using the 4017 outputs to drive bc547's transistors that turn on the LED's, again with different arrangements of caps and resistors on the base and/or emitter sides and I've also tried resistor/cap arrangements that can turn square waves triangle or sine, with and without the transistors. In all cases, I can get a very controllable fade out of the LED's but cannot get them to fade on. Is there something about the output of an LM4017 that will not allow it's waveform to change or for a capacitor to slowly charge? Or something else that I just can't figure out?
Super...😍😍😍😍😍😍😘😘😘
Thnk u so much😀
There a simple way to make the LEDs slowly come up instead of just on/off? But still do the chasing action
sir, is it possiable to give clocl puls with a push switch instade of 555 ic?
what is the work and how to use enable pin and carryout pin?
and thank you so mutch for this video.
whats more required if I need to make a long led chain like for 200 LEDs
Good job, how can i use more than 12 led
how do I connect variable resister varying voltage supply?
Sir great video Thank You.Are you able to tell me how to make it variable speed? I'm planing my Christmas lighting and would like to make one of these to run slower.
Replace 47K resistor, with a 100K potentiometer (Any two adjacent leads of potentiometer connected in place of two leads of the resistor)
Nice video
do you have a tutorial about running light ??
plz provide guidance for usage of potentiometer
Good day Im making a brake like for a motorcycle and need a little help. I want a chaser but i want it to chase/run just once and stay on. How can i do this
*Thank you whooo*
will work in series if I only use 3 LED
s?
I want a basic police style led flashing unit using 4 leds in each module. both units will be wired into the car and into switch. Similar to the conceled lights hidden in the grill of the car.
If you can help me I'd be ever so grateful!
Thank you ☺
nice
I got my circuit to do this. But how can I make all of the leds come on at the same time and hold the charge?
OK thanks
If ut LEDs aren't visibly flashing, try -
Increasing the value of capacitance and resistance
Will this circuit only light up when all of the leds are connected to the 4017? I’m almost done and tested it with one led and nothing happened.
Hats off
And also the value of variable resistor
Can we use IC4017 in place of CD4017
sir...how many blue leds can be control by this ic...
and can I connect leds repeat and repeat 100 leds...
for this what is the voltage I need for....plz answer me.
How i can increase the no. Of led
If it require transistor then of which no.
very nice yar
Hello. I'm trying to copy your circuit in multism. You don't have VDO and VSS assigned to anything. I can't get my simulation's LEDs to flash. any pointers? thanks, and nice job.
Both the terminals of the 470R resistor are connected on the same rail. is that intentional?
TI has a CD74HC 4017E chip. Is it the same as the 4017IC chip? Fantastic video, by the way. I thought I could only achieve this with an Arduino!
I did this circuit long time ago 😂
Hi,
I gave the same connections and used a 9v battery and only the 2nd led is lighting up and no pattern is there . Please help
A small complaint of the note on the web page: "Note: VDD/pin16 of 4017 IC is connected to negative terminal of battery ('D' for drain), VSS/pin8 of the 4017 IC is connected to positive terminal of battery ('S' for source)" In reality pin 16 is connected to the positive of the battery and pin 8 is connected to the negative. VSS vs VDD can be confusing.
Can I use different led colors?
