CD4017 tutorial: the IC you can count on!

Great work Jens. The quality of the video production is really going great. We can see the effort that's going in, thanks.

Impressed by the amount of work that´s been done to make this video. A big thank you.

Awesome video! Neat explanations, circuits and editing, thanks a lot for your work :)

What an absolute pleasure to watch. You're very clear in your voice-overs and the animations are really helpful. I will definitely build this when I have the chance.

Great video, I learnt alot. Thanks!

Just finished building this circuit and learnt a bunch, so thanks a bunch. 😊

I might have misunderstood but I think the Carry out is high from output 1-5 only. Thats how my 4017 works.

you are too good

Just explain about what is pull up and pull down resistor with practical....could you?

how does the reset circuit produce the initial start up pulse when the reset pin isnt connected to VCC? as i understand it you need to make the reset pin high to activate the IC so if the reset pin isnt high on startup how can the output go high?

you deserve so many more subs. really great video. thanks a lot

I let the IC cycle through 8 steps with just the 555 (no buttons for next step or reset), but every time I power up the circuit, it does one cycle perfect and then skips the first output Q0 every time. How can I fix this?

Thanks bro. Thanks for the very detailed explanation of the 4017 IC!

Thanks so much Mate. What a fantastic tutorial. Push button bouncing, haha. I thought I was wiring up a previous project incorrectly. ;-}

Very nice

I liked and subscribed. This takes a lot of work. Does each LED really need its own current limiting resistor? They can only be on one at a time, right? Looking forward to more vids.

Hello, please how do i count backwards? is there a way? thanks

This is really cool and helpful, but as a CS person I hate that reset circuit. Fixing a race condition with a timer never works long term. This should be a latch that unlatches after both resets happen.

can you create a separate video on IC 555 timer ? and few simple projects based on IC 555 ?

Wow, thats amazing. I would love to build this kit. Quick question, can this be powered by a usb cable with a power bank as a battery? I know that it would probably need some modifications on the resistors, but would it still work?

Your videos are like Peter Jackson movies ,pristine and eye catching .I'm new in electronics I'm a 50 years old guys always love electronics ,learning alone with some books and videos. LOOKING FOWAR FOR MORE OF YOUR VIDEOS.I have a question 🤔 can I use ceramic cap.? Also it's there a equivalent for 1N4148 diode ?.I have a lot of them but not this one you know how it is .Thank

incredible explanation 🔥🔥❤️❤️❤️❤️

Maybe you could use a rs flip flop which is set by the "and" condition q1.6 and q2.2. For reset you use another "and" condition q1.1 and q2.1 🤔
Unfortunately I don't have the opportunity to test this, but I would be very curious to see the result 😊
Sorry for the grammar, i'm not a native speaker 😅

Just for the meme, I would have made this a 10-step tutorial. The carry out counting to 99 is fine but I would have liked to see implementation of a count to 19 circuit as I think that's also quite useful. You could make a followup video called "Hey 19", again for the meme, a reference to the Steely Dan song.

your circuit wiring is like a work of art!

Great video. I stumbled on this looking for something very similar. I basically need your exact circuit, but I need to be able to also count down as well, using a separate momentary switch. Do you know of an IC that has the 'down' option? Thanks!

Use a resistor in conjunction with denouncing capacitor C3 to prevent premature contact erosion. Insert the resistor between S1 pin 1/2 and C3's + lead. A typical value range would be 10K to 100K ohms.

A really easy tutorial. I had to redo the wire so it was clean looking. Not as good as yours. I got several CD4017's just because of this video. Thanks!

You had a train to catch, slowly man we learn!

Can the green led starts to lights after the last yellow led
I want the led to light in sequence like (1,2,3,….20) not as the video in the same time (only one led lights)

which editing graphics software your using ???

can i ask how can you make it reverse and forward counter using 2 buttons

❤

VERY NICE PIECE FULL CREDIT WHERE ITS DUE THANKYOU FOR THE CONCENTRATED VERY USEFUL TIPS

Thank you very much man

Great video… you can eliminate all those resistors tho… tie the cathodes of leds together and run them to ground through 1 resistor ( I used a 560 ohm resistor with a 9 volt supply and it worked fine( only 1 led is being turned on at a time so no need for each one to have its own resistor) Thanks for the video. I subscribed ❤

I'm going to build a binary clock with this

Great video, super helpful!

Thanks!

nicely done! my understanding of electronics is rather shallow so I mostly rely on tutorials when making something and they just rarely explain some of the used components. So the information like "what voltage and why can some component handle" or the way you first show the trouble created by the button and then shoot it with a capacitor instead of just placing it there right away, makes a lot of difference.

Keep up the good work

What application are you using to design circuits?

Wow! Perfect video! Thanks!!

Great video explained extremely well thank you.

Hello, thank you for sharing the detail of your work, it is very inspiring!
I am trying to make a cascade with 4017 and 4081 (and gates), I have built the circuit more than 15 times, but I have a problem: As the speed of the sequence increases, it loses the order. Some steps are sped up compared to other sequences.
Please help, what do you recommend I do?

❤

thankyou so much ❤❤❤
your video helped me to learn CD4017😁
