LED Chaser circuit using 555 timer + 4017 IC on Breadboard - Basic Electronics Projects

A tutorial on how to make an LED chaser circuit / sequential LED flasher using 555 timer IC, CD4017 IC on a breadboard. Working of the circuit is explained at the end of this video.

Link to the circuit diagram plus more info:

Components Required:
* 555 Timer IC
* CD 4017 IC
* LED Lights x10
* Resistors: 470R, 1K, 47K
* Capacitor: 1uF
* Breadboard
* Lot of Breadboard Connectors
* Power Supply: (5-15)V
NOTE: If you are using a power source more than 9V, use 1K resistor in place of 470R.

This channel has a lot more electronics projects & 555 timer projects. So feel free to check them.

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!

Your explanation for the circuit is unique and useful
There are many YouTube 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
Explain well keep it up ....
Do more videos ....

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.

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 YouTube. Please do keep them coming. Thank you :)

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 ☺️

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.

Any insight on how to modify this circuit to use the trigger source as a piezo crystal?

[davyps]

Thank you so much to all you good folks who share their time and knowledge on these sites. Great

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! 😊

Very Nice & Circuit Was Working
Thank You💐

[lokeshherio]

I just love this ckt. finally this ckt is working.. God bless you bro....

[alanturner]

Watched this a while ago just came back to add parts on to my shopping list, looking forward to trying. Great video thank you

[Ourshorts]

Awesome and very helpful video for making Minor project but I prescribed that use"JUMPER WIRES" INSTEAD OF connecting wires .once again' very thankful for this wonderful explanation..😊

[s_s]

Awesome and right to the point. I love it. Thank you for this. Great work!

[greenmaniacs]

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.

[dariocar]

The project works great, which value off the potentiometer should be replaced in who resistor?

[branebaronk]

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.

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!

[asanmodhu]

I felt good bcz I succeeded my first Thanks a lot sir

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.
