This is a Rain LED circuit using a NE555 and a CD4017. I have divided this circuit into two parts, the first with NE555 generates an (adjustable) frequency which issent to the CD4017 (Pin 3 NE555 to Pin 14 CD4017) The second part of the circuit, with CD4017, manages the LEDs, making them run at a speed set by the frequency that I just told you about (from NE555). LED speed can be adjusted by a 47KΩ trimmer.
After trying the excellent service offered by JLCPCB I recommend it, the quality of the PCB is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier. JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 5 PCB Boards (Any Color) for 2$ !!!

Ordered a bunch, looks a good project to practice THT and fun for Xmas. JLCPCB are good. Just have to watch for high shipping costs for priority mail.
Just finished assembling! Thanks for this project and the excellent gerber files. This will complement the aesthetics of my Star Wars Trilogy arcade project tremendously.
Hello, thank you very much :) I try to help you, as far as the power supply is concerned, a lot of current capacity is not required (at 5 volts it also works by powering it via USB) - however it is important that the voltage is DC. I hope I understood what the problem was!
Okok, share the link here, if UA-cam were to send the comment for review I will approve it manually
I found the problem... a bad wire. I edited my original comment above. Thanks much!
Sweet! Also, 5v means you could use a USB power bank to make it portable or wearable. 😊
The Christmas tree with no decorations, except for this cracked me up! 😂 Another fun project, Definitely going to get some of these PCBs with my next order. Thanks!
Thank you =)
Don't be scared I was starting to decorate it and I took the opportunity to record this clip😂😂😂
And it work via USB: ua-cam.com/video/3IUJcIZ2bvY/v-deo.html (video extra)
Ciao dear friend Stefano! What a wonderful project usable for christmas :-) I have already odered 10 pcs of it! Wish you all the best! Merry christmas, Boris, Svizzera
Hello Boris =)
Thank you! You'll see, you'll have fun assembling it =)
@@Stefano91ste
Yes Stefano I think so. I‘ve tried to build something like this and I used capacitors to make the Leds go out slowly. I used another IC and it went okay. But after 1-2 minutes the circuit stopped working..? I don‘t know why. But yours looks great even with no capacitors! Cheers, Boris. 🇨🇭
Hi Boris! - it is difficult to understand now, maybe some component was crossed by too much current and burned out, sometimes big problems can be solved by add a small resistor (it's just a guess based on my small experience of results and failures xD).. I find your idea of capacitors very interesting, I didn't think about it.. so I would have obtained a wake effect like KITT in Knigt Rider TV series =)
Very good 👌
I Subscribed 👍
Thank you!😁
...e anche questo ha raggiunto la mia lista della spesa. :-D
Ciao Luigi! vedrai che ti divertirai a montarlo!! Grazie =)
Had some boards made via JLCPCB, kept options default with "slow" postage and costs were low. Worked well, once I put the LED in the right way round. 🤪Which was good practice for learning to unsolder components and butcher a PCB back to life. Still, you learn a lot from mistakes. Assuming you don't die trying.🙂Seems fine on lower voltages (~5V). Nice project. Thanks ...
Amazing work🙏
excellent👍👌
Thank you:)
@@Stefano91ste sir I want to make circuit for 10
led(right side)
+10 led left side
one side led chaser,
Is it possible in this circuit?
Bellissimo! La scritta Rain Led sul circuito per indicare il nome del progetto è un tocco di classe! :D
Grazie mille Teo 😎😎😎
Mantap dan keren 😎😎😎😎😎
Ciao Stefano. Belle lucette/progetto. God Bless. t\.
Ciao, ti ringrazio!
Nice
Thank You =)
I thought you will make POV
Bravo stefano 👍😉
Like e follower da tempo ormai.
Ma non ho ancora capito come funziona il sistema per farsi mandare e fare le basette dei circuiti
Grazie mille😁 in pratica per ordinarli puoi scaricare il file del PCB, ogni video ha il link al file del progetto specifico, poi carichi quel file sui siti di produttori di PCB (io uso jlcpcb) e loro li realizzano.
Stef, how many lights can you add to this before you have to up the voltage? If I use smaller 3mm lights? I was thinking of this for my mock airport center runway lights.. What do you think?
Hi, You can put 30 LEDs without problems, in parallel as in my diagram but in groups of three, 3 or 5 mm is always fine. I like your idea of using them as runway lights😎
@@Stefano91ste Well I have my toys I need to upgrade ya know.. and at 68 years old I have a lot of time for upgrades.. I was thinking of doing that to my 18' aircraft deck I have built out in the back yard to land my rc ww2 fighter plane on also.. But I am not sure they had them on the old carriers.. I will have to look it up.. thanks brother I appreciate all of your hard work.. especially the board schematics I can send to have dome boards made. You so a great job here. Carry on and have a Merry Christmas..
Do well! it's nice to have a lot of time for your hobbies :) Thanks for the comment!
hi E P S...
'
very beautifully LED kit
Hi bestamerica, It's not a KIT, it's a PCB that I designed =)
@@Stefano91ste
hi E P S...
'
very good design as project
Cool
Thank you!
Hello again! Which component would I change to achieve an even slower scan rate? The capacitor? Thanks!
Yes, If the slowing down of the potentiometer is not enough, the values of the capacitors must be modified
@@Stefano91ste higher value?
@@JohnEricBooth yes, higher
Circuit diagram please sir
These circuits I did when I was little. Where are you from?
Hi, is always a good circuit! I am from Italy, you?
@@Stefano91ste España
👍👌
How many leds will be added
Hi, 3 LED for any channel
hi can i use 50k potentiometer answerplsssssssssss i need answer
Hi, Yes 50K is OK
@@Stefano91ste ok thank you
Needs Gerber file
Circuit diagram pls
Watch the video from 0:25 (circuit diagram explanation) and at 5:50 for clear circuit diagram
Explain the circuit diagram instead of music
The explanation of the circuit starts at 0:27
Circuit diagram please sir
Hi, read video description for circuit diagram
