LED Fader using LM358

[robbe8282]

@robbe8282 i'll be running 12v, it's going to be inside a pc.

Wow!! Great job:) Can you send it to me please? My son would love to do this with me!

Is there a way to randomize when the light comes on and can you hook up more then one LED and have them all come on at random times all fading in and out? Like fireflies:)

I would like to have a copy of the circuit..and im planning to do up this circuit for my motorcycle with some led strips bought from ebay.As the strips are already installed with resistors,do i need to modify the circuit?

Thanks a million :)

How to speed up the frequency , I need it to light up more faster and turn off .. but I don't want to change the capacitor , can I just change the resister value to get a faster effect ( using a variable resister ) ? and which resister to change ... ( I need it to operate normal speed just like in your circuit to about 100 cycles / second

I would like to have a copy of your schematic as well if possible. Thanks!

Can you mail me the schematic pls?

DVD_Keene@yahoo.com

And maybe a brief explanation of how it works exactly?

Thanks!

This would be possible without the cap right? I could use a pot instead?

[Sparrow338]

@slightlydrybeans: The capacitor is necessary for this circuit to work and it could not be replaced by a resistor. It isn't actually possible to ever replace a capacitor with a resistor or potentiometer (aka variable resistor). However if you replaced the fix capacitor with a variable capacitor this would work. But variable capacitors with values high enough for this circuit would be likely big and unpractical.

Does not work. The LED stays on all the time ;(

Help me!

....Thanks for the schematic. ^^

[Mercado2808]

great!

I am interested in your circuit, you could send me?

thank you very much!

[ZAKK9090]

Hey can I get a copy of that schematic? This is exactly what I was looking to build.

Send to zakk9090 (at) hotmail, if could please.

Thanks in advance!

do you have a schematic you could send me or post a link to?

[innuendo9999]

HI, do you have the schematic?

thanks

[julieail]

so is this a sine wave?

[Sparrow338]

@julieail: It's actually a pure triangle wave. Although a sine wave would give a similar, if not identical, effect. This circuit setup is capable of making a sine wave though.

[julieail]

@Sparrow338 can it run off of a 9v battery?

[Sparrow338]

@julieail: Yes it can run from a 9volt (it's running from one in this video). The LM358 IC is good from around 3-35volts. I think in this set up it begins to stop oscillating around 5 volts and is good up to 35volts. Make sure you use the correct resistor in series with your LED/load.
