Absolute legend. Just what I'm looking for. Thank you very much for this video!
Glad it helped!
hi , I have built a chaser circuit using the 555 and 4017 , could you tell how to introduce fading effect during transition of one led to the next. Many thanks
Thanks for the videos. Wonder if you know how to make a circuit with a capacitive touch switch which would slow fade on and off 12volt LEDs when touched.
Thanks for the video, a schematic would be helpful😇
What changes must be made to power this with 3.7v?
This is for an outdoor solar project.
What capacitor use in 12 car dome light fade on-off?
Hello! Can we use 5v and remove the resistor?
Exactly what I was looking for - thank you for the share - need for model transmitter tower w/ red lights
Glad I could help
No pun intended. I watched this video from multiple screens and without a doubt @0:48 the value of the resistor is 33KΩ (Org,Org,Org) instead of the 200kΩ (Red, Blk, Yel).
Nevertheless, thank you for sharing!
thanks
why only fade in but not fade out ?
This does not fade out
Hi and thanks for the video but I have a small problem when connected the capacitor it goes off then glows nicely on and bright but stays like that, I changed all components and the same only thing is that caps is 30V any idea why thanks
try to change your IC and capacitor
It didnt work for me. I tried two different ic 555, bc547 and a 12v power supply. Just light up and didnt fade out. I changed to 10uf, 1000 uf and just light up and no fado out.
re-check your connections carefully
@@IdeasTv I have to put a resis 470ohms at led vcc+ to the transistor to make ir work.
What is the exact resistace is, is it 33K or 200 K ? with 200k it doesn't work.pease guide me.
Hi if I had 6 leds in a circuit would I need to make any alterations? Capacitor size or resistor size?
Thanks
no just connect the LEDs in parallel combination
I want to connect use 2 leds to get this effect with 2 12v battery which is connected to solar panel using charge controller. will it work ?
yes
So I have it working but as soon as I put in the capacitor it just stops working
My BC547 is getting too hot in a few seconds and smelling like burned. What should I do?
check your connections and your battery amps
please attach the circuit diagram....it would be even more helpful
Can you please explain exactly how the circuit works? It is not a simple circuit. It is very clever.
Hi. I tried but the led only fade in but not fade out. I used a 100uf capacitor with 50v as i could not find a 25v. Is this the reason why it does not fade out? All the connections are triple checked on my bread board.
there's a strong link between fade in/out of LED with capacitor and it's capacitance so try to change your capacitor
It worked. Thanks! Can this circuit work on a 12v LED bulb which is led 3014 bulb used in boats or cars? I've tried connecting it but it does not work. When I removed the capacitor, it lit up but does not blink. Only a normal 12v LED worked.
If changing the DC to 5v, is the resistor the only thing I'll need to change in this same project?
Is this fade in & fade out effect is while the DC on? Or fade in when turn on and fade out when turn off?
no need to change, to run this circuit on 5VDC. Yes, but in fade IN/OUT phenomenon IC slowly decrease or increase the voltage instead of completely cut off.
@@IdeasTv Don't need changes? Even the resistor? The LED won't burn out? Thank you so much for your attention!
Is it necessary to use 12v adapter ???
And good job thank you 😍
You're welcome
Good circuit... slower fade out would be beautiful.
The 200K resistor you show in the video is not 200K (color code wrong). Also, this circuit will not work on 9V no matter what I do. (I'm an engineer so I know what I'm doing....) Perhaps you can verify? I'm also using a 2N2222 transistor which is equivalent except different pinout. Won't work at all.
Same here xD
No luck here with the same setup you have mate
I did get it working, with a 1000uF cap but it flashed way faster than the vid and i added a 330 ohm resistor because i blew an LED without
Add a switch into that?
Can this run at 3V? I have a small solar light that I want to convert as the topper to a garden lighthouse
yes
@@IdeasTv Excellent. I'll let you know how it works out
@@n1olo and you never ever let anyone know....
@@IdeasTv can I use 12v on this circuit to have the effect on the 12v led?
Nice sir Plz explain me If I want to use 24 LEDs or 48 am i can use the same circuit?
use LEDs in parallel with 12V 1A supply
Is it PWM?
Can I use a different transistor for the same result?
you can use 2n2222 but bc547 is recommended
Can I use a 12V adapter with 5A?
5A is high, can reduce the circuit life
Is it work with 5m neon flexible?
voltage ?
@@IdeasTv 12v
Bro i want to do this with a 3 watt led bulb ... Plz help
you can do it
I got it to fade in, but it's locked "on"... I am using a H945 transistor but the characteristics are pretty similar.
Use BC547, apparently it's look like this is due to the transistor.
Im using BC547 and having the same problem 😔
can you use 9 volts or does it need 12?
9V
Ok thanks a lot
what would need to be changed if powering from a 9v battery?
no change required
Does not work at all
Only fades in never fades out
Can we do this experiment with 9v battery?
yes
What happens if you do this without the transistor?
Nothing happens :D
Note to self: Capacitors can explode. Wear safety glasses all the time
Will work with 5v?
yes
Do we need to use 555 timer ic. Is this circuit valid without 555 timer ic??
no 555 timer ic is required
Thank u
Finally, the resistor is 200k or 33k, as the color code seems to show?
For me, with 33k, it does not work!
Mine stopped working, so I built a new one identical: now both of them do not blink. They fade in and only fade out when I touch PIN number 5 !?! What am I doing wrong???
No proper ground or vcc, re-check your connections. make sure that there is no loose connection on GND or VCC
Ideas TV naw, I soldered them together... I’m using a 200k Ohm resister at 5 Volts, led output about 3 Volts (Perfect!!) at 47uF capacitor... should I just lower the resistor to... I dunno 150kOhms?
Cuz when I moisten my fingers and touch both ends of the resistor, it blinks like a charm! 🤪
Hi, great video! If you lower the voltage to 5 V, will the 100 uF capacitor still fade in and out at the same rate? In other words: will the voltage only influence the brightness of the led?
And: is the capacitor 16 V or 25 V?
Yes there is no relation b/w voltage and fade in or out rate, and you can use both 16v or 25v capacitor but 16v is recommended here.
Ideas TV thank you so much!!! 👍🏻😀
It’s working!!! Though with the 100uF capacitor (at 5 Volts) the fading interval takes exactly 40 seconds. I’ll try it with 22 and 47 uF.
Thanks again though! I’ll post the result in a while in an upcoming diorama video!!
Probably a stupid question, but with 100uf 25V capacitor, it blink fast AF !! Is it normal? I will try with 16v this week...
@@heyanctilpui In my case it doesn't blink at all... the only difference I have is that my resistance is lower because I only have a 7.5V supply
Idk why it isn't working
how to do it on 12v led strips?
use high voltage NPN transistor on LED out.
To everyone trying this: put an extra 330R resistor before the LED or the LED will burn!
It works but not even for 2 secs....what can I do..wanna change my capacitor ah?
please help me this circuit created
Can u tell me 200k how much watt.
1/4 watt
circuit copy, send please
will 1k resistor work?
Thanks for the video. This worked for me .. I used 22mF cap and 5V DC supply
Keep supporting :)
The music is very unpleasant and distracting.
👍
ahora ponle una strip
hi, great stuff, congratulations, i'm making a miniature lighthouse, i need for example; a 6.5 sec obscure period, followed of 1 second of light. total period of 7.5 sec. and also i´m making a bouy, a 20 sec full period with 4 flashligths, ¿how can i make those?
Did you find a circuit to do that cycle?
It doesn't work once it fade in the LED will stay on.
re-check your connections or just try to replace the IC
its not working please help me
yes?
@@IdeasTv im using 4.5 voltage battery. must i use whic resistance and capasitor? and my leds working 4.3 voltage
Not working ☹️
re-check your connections
@@IdeasTv kya LED ka problem b ho sakta hai, blue LED parmanent on thi, red LED me on- off to hai lekin feding function nahi hai
It does not fade out
re-check your connections and capacitor.
Horrible music
This made my project complete! Thanx! th-cam.com/video/MVVpZLRVkAQ/w-d-xo.html
I put a link to this video in my description!
just watched final product, good work!
@@IdeasTv Same to you! 😃👍🏻
