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 UA-cam. Please do keep them coming. Thank you :)
Your explanation for the circuit is unique and useful
There are many UA-cam 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 :)
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.
Thank you so much to all you good folks who share their time and knowledge on these sites. Great work!!!!!!!!!!!!!!!!!!
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.
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
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! 😊
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!!!!!
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
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.
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?
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 ☺️
Any insight on how to modify this circuit to use the trigger source as a piezo crystal?
bro i think it's my flt but plz help me i did the circuit but it works but in a weird way when i turn on 1 led opens then i turn off then turn on again other one and sometimes more tha
n one opens ?why?
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?
The project works great, which value off the potentiometer should be replaced in who resistor?
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.
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.
Very good tutorial. Nice job editing. Thanks and subbed
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
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.
Both the terminals of the 470R resistor are connected on the same rail. is that intentional?
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.
How to rig up a roulette led circuit please help me put I m nt getting how to connect the led's??
how do I connect variable resister varying voltage supply?
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.
Mine only seems to blink on led 1. The rest don't come on at all. I've rebuilt it 4 times but just the same result.
Help would be appreciated.
whats more required if I need to make a long led chain like for 200 LEDs
How do you make the circuit stop after 1 sequence?
you said to put 1k resistor between pin 7 and 8 on 555, it doesn't look like brown black red which is 1k. can anyone clarify please ?
Do you have idea how to change cycle time delay?
But same speed chasing
There a simple way to make the LEDs slowly come up instead of just on/off? But still do the chasing action
Brother if we want to add more LEDs how can we change the circuit?? And how the circuit is??
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?
How i can increase the no. Of led
If it require transistor then of which no.
I just want to ask can I use 57k resistor in the place of 47k resistor
nice, clear video - thank you!
Hello sir,can u give us advantages, disadvantages and applications of this project?
Good job mate, really appreciate your time and effort... 👍🏻
will work in series if I only use 3 LED
s?
Very good explanation. Thanks you very much.
Can we use IC4017 in place of CD4017
Bro please help me. My circuit is same to you but it is chasing only when i am again and again plugging power in and out please tell what to do please i have less time
I just love this ckt. finally this ckt is working.. God bless you bro....
I make single flashing led with 555ic but there is a problem led Glow permanently I am using 1k,1k 470R and 1microfarad capacitor can you explain how to solve that problem
Amazing video's! I have a lot to learn to get my video's to the same level! Great work!
Can i use any other capacitor like 2.2 uf
What are the numbers on the brown capacitor?
What if I use a 0.1uF capacitor in place of 1uF?
why the source needs to be 220v for the circuits to work on electronic workbench?
Sir Your explanation is really really awesome...pls make a project about on water level indicator. Thank you.
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 ☺
do you have a tutorial about running light ??
Can I use different led colors?
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 :)
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!
Thank you it worked after 2 tries
What do you do if only the first led lights up
Hey what to do if i want only 8led
If I want to make the Sequence slow means 1 led glow for 5 sec, and then another will glow. so wat modification I can do
First thank you for this vidio is was east to follow an worked first try however when I try to put more than 4.7v to it it acts erratically all LEDs flash very dim in unison with a random one will flashing brightly both my ic's are Texas instruments and I've tried swapping them thinking one was faulty if you can please help.
From the datasheet, both the IC's should work fine at voltages up to 18V. It can either be that some of the connections are loose (Maybe the clock signal?) or there might be shorting somewhere on the breadboard.
Where do I add the potentiometer to the circuit?
Sir ,Need help the led blinking is too fast what can I do ,what I did wrong 😟plz tell ,what do I do
I was looking for this exactly (for led strip). Thanks.
can uh provide me the pcb schematic for this circuit...?
I need more details abt this circuit....give some reference websit
well teacher and very simple method of building circuit......
Can you degsin to glow all led one after other and lastly off all ,again glow one after other when completed all led then off all at time please sir
how many leds can be fixed to an 12volts input
Can we use 1.7k instead of 1k ?
where did you simulate this sir??
Subscribed for your circuit explanation keep making videos
Good job, how can i use more than 12 led
Sir, I don't have 1uf capacitor so can I use 10K PF capacitor
It worked wonderfully thank you
Well explained and clear voice
It's very clearly explanation... Thank you so much... Keep it another all videos... Thank you...
I have subscribe for the first time at any youtube channel.well explained buddy..... 😇😇😇😇😇😇😇😇
lokesh
l
It's OK use 74hc595 or not
Where can I get the small 3-led strips that are shown used with the potentiometer?
Can you buy them like that or have they been cut from a strip?
I have cut them from a longer strip
is there a way i can use ac voltage for this? im making a project and it involves using 220 v ac and i need to make my running lights project work, what parts should i use?
It's better to use an existing mobile charger adapter that gives out 5V to power this circuit. This way it's easy and less complicated
how i connect the potiontalmeter
Great tutorial, thank you
Hi there! I was wondering how could I make the leds turning on and off up to 3 times each one before changing to the following one. Thxs!
Hi, instead of directly connecting the cathodes of all the LED's to negative rail,
connect them to the output of another 555 timer configured to provide 3 pulses for every one pulse that the primary 555 timer provides.
why we want to use the 470r and 1k resistor
Id like to make a 7 LED chase light. Do I remove some of the LED's in the middle, the end or do I need to do something completely different?
Just remove the leds 8,9,10
plz provide guidance for usage of potentiometer
Exellant job brother. ..greetings to you from Bahrain. .👍
Very useful video with nice explanation. Thank you and please share some more .
Sure. You can watch all the videos here: ua-cam.com/users/elonics
how to connect potensiometer with ne 555?
Amazing explanation sir
ye led chaser kaha milega
Sir my Leds are blinking together....What should I do?
only 3 Leds are blowing what is the problem?
can i use a 9v battery? will something happens to the circuit or the circuit works the same? very informative video good work sir.
I felt toooooooooo good bcz I succeeded my first project........ Thanks a lot sir
RESISTENCIA 4.6 Kohms?
I understand the clock pulse and the transitioning of the shift register, but how does the "1" get into the register in the first place and then not turn back on until it's completed all registers?
4017 isn't a shift register but a Binary to Decimal counter
