This 10 Channel Running LED Chaser is made of - BC547,BC557, NE555

Hi ,
This video is to show you how to make a 10 channel LED chaser circuit using transistors and 555 IC.

I did the same, buh didn't work so I followed the diagram and it works so cool❤️❤️...hoping to get more from you sir...THANKS ALOT...!

Nice design, but in the schematic the 120k resistors are connected between the bases of the transistors, while in the video they look connected between the collectors. Which is correct ? Thank you.

Beautiful project I would like to use it to build a barrier of LEDs to form a cascade of lights, listen how to have much more speed? thank you

As always amazing works from your channel. Is it possible to use a 12V power source in this circuit? Or would it be necessary to size the resistors and capacitors? Input supply voltage, 4.5 V to 16 V according to datasheet.

Successes and a big hug from Brazil

Like in the video, but 5 channel
Thanks 🙏

What to do for if i want supply from 5v smps instead of 3.7v battery?

[tuepham]

do you use the PNP or NPN version of the 557 and 547?

[vinniejones]

Without a circuit diagram there is absolutely no chance of fault finding if this doesnt work when you try to follow this.

Is there any IC that can replace so much soldering?

En los años 90 lo hice y bi direccional

It would be nice to have a circuit diagram for the "Breadboarders"

[jinuvnair]

Please explain how 10 leds are controlled separately by a single timer output?

Brother Sam system 30 led ka bana ke de sakte hain

Jldi jldi cuneksan kr die kus smj nhi aia brre aram bolkar samjana chahie taki anrri se anarri ki smj aa jae 👍

Not working it will blowing please help me

[hengkyboy]

boss please share the schematic🙏 thanks

Please don't try this you are wasting your time

Required Led chasers circuit which return back also just like Night Rider KITT
