Thank you. For anyone who wants to know how to drive a more powerful LED or other load like I needed (3watt LED) I used a TL431 MOSFET to drive the load of my LED and used a P2N222 transistor and tied the Emiter pin to the Gate pin on the MOSFET. FYI if you are having any problems with the light not flashing and only staying on I would recommend swapping out the resistor that is between the two pins on the 555 with a variable resistor and slowly adjust your resistance until you get the flashing look you want. For my setup I found that a 330 ohm with a 16v 2200uf cap along with the TL431 MOSFET works great! Oh I'm also using 9VDC.

Any chance you have a schematic my friend?

Would you be interested in a small business transacton? I need a slow breathig cicuit for 20 LED's. I have watchd over a dozen of these "Breathing LED's" videos and NO ONE seems to be able to produce a video wth 3 or more LED's. I need o drive 20 LED's, each having a forward voltage of 3-3.5 and run off of a 7.4-14.8v battery.

TL431 IS NOT A MOSFET. It is a shunt voltage regulator. There is no P2N222 Transistor. Do you mean 2N2222 or PN2222??????

Hint: To better maintain your sanity, lower the volume to zero while watching this.

It worked. Thank you so much... :)

FYI: This circuit doesn’t work well on 9 volts but it does on 6 volts.

Perfect! But I need trimpot! How to connect?? 10K 100K 150K 10 Ohm etc???

Use a 100K (103) trimmer pot in place of the 100K resistor. You can also try different capacitor values. Larger value = slower ‘breathing,’ smaller value = faster.

Hi there: mine fades in beautifully, but stays illuminated!? When I physically thouch pin no. 5 it fades out.... any idea, what I’m doing wrong?

Same. Then I used a power supply and found this circuit ONLY works on 6 volts.

Sarah Michelle I did get it to work on 5 volts. I built 3 of them and one day all three didn’t blink independently from one another?!?! My guess is the weather has some sort of influence on the resistor as well .... lol

Hey there! Even i had the same issue and i replaced the transistor with 2n2222 and it works just fine! Try replacing the trans and you should get the expected glow

Hi Great Vid followed all of it, but but im now stuck on the voltage value of the Capacitor i'm assuming 50v?!

Capacitor voltage doesn’t really matter. However, what is not shown in the video that DOES matter is that this circuit ONLY works on 6 volts, not 9 volts.

@@Sarahbuildsstepsequencers thank you for that gem, I tried 10uf @25v with no impact, i then tried a 4.7 + 2.2 uf at 50v, and got the led flashing, but maybe the 7.4 volts I'm using is too much, wish knew that before buying all the bits, maybe i can use a resistor to lower the input voltage from 7.4 v to 6v, which resistor would you recommend i use?

Frank Grimace not sure. You could get a battery holder that fits 4 AA batteries, though.

how does the transistor part work, isn't it an npn? youre powering it with vcc

@Jari Kokoru yes please translate

I do not understand why you use an NPN transistor and connect its collector to the VCC. Would make more sense to have the emitter at GND and have the LED at the collector... From a theoretical standpoint, this cannot work. I suspect you are using a PNP transistor such as bc557 instead.

What changes could be made to make it fade in/out even slower?

Back Into Fishing To change the speed you would need to increase the size of the capacitor or change the resistor

guy, please the circuit

The second rail why it's not connected to - + power, it's not work honestly

To have the fading in and out go more slower and have more time between on and off you will have to increase the capacitance. That means replacing the capacitor for a bigger one.

Future Videos? HOW ABOUT ADDING SCHEMATICS - it's painful watching people mess with components.

@jp040759

Ай бұрын

HOW ABOUT SCHEMATICS!!!!!!!!!!!!! Video is WORTHLESS without schematic.

I am quite surprised. All those who have posted their comments (Except One, whose concern was somewhat skewed) have failed to observe that the BANDA has connected Vcc to collector of BC 547 and states "Emitter" in place of "Collector". Also the colour bands of the resistors don't agree with the value of the resistors indicated in the video. So my humble request to all & sundry; Just Observe minutely, then verify and then only comment. Electronics like any other branch of science does not tolerate NONSENSE! Take care.

Very nice, I'm happy for you. But, what's the point ? To show off ? One can barely see what you do and if you want to share and help, give a schematic...

It's just fake, other rail not connected each side together
