Great video! What if I simply wanted to have the led's fade in/out only when pressing the switch. When you turn it on, it would fade in and stay at full brightness. When you pressed the button again it would fade out to off. Any suggestions?

@RafaelMarrero86 You wanna make a toggle switch and connect it to this circuit. Use a flip-flop connected as a toggle switch.

[RafaelMarrero86]

@pcbheaven Thank you so much for the reply! If I understand you correctly, using a toggle switch would achieve my desired effect, as the video is using a push-button switch that has to be held down.

[pcbheaven]

@RafaelMarrero86 a toggle switch is one solution to your problem indeed. But you can use an RF flip-flop chip and connect it as a toggle switch, and then use a simple pushbutton which will work as a toggle switch. Search for "flip flop toggle switch"

Nice circuits!

tell me what value of capacitor did you used??

I've been looking for a good project to make fading LEDs. Most examples have PICs and I wanted it to be analog, so this is great. Thanks!

how can i power with this

20*0.5W 3.0-3.8 V 150ma leds

Hey what is the small black one called?? i was also in on your link.. and what does Q stand for?? thanks.

[williammjs]

@magnusrulz both are transistors

[ciprianwiner]

well i made the more sophisticated one and the values of the parts are near the same and it works great and it's hard to make it so thanks alot :D

@ciprianwiner ;)

[mariomusico2010]

its circuit is simple but very interesting for me to work with professional lighting with LEDs will incorporate it into my desk RGB Controller

[dedasdude]

thanks a lot for answering my questions!!

[dedasdude]

i was also wondering, from your LED flasher circuit, if we can add a capacitor and a diode in parallel to the LED array, it would give them a fade in and out effect right?

[pcbheaven]

@dedasdude if the capacitor is large enough...

Μπραβο φιλε μου.Παρεπιπτοντως το site σου παει στα αγαπημενα.ΕΥΓΕ

[dedasdude]

awesome!! i was thinking of this thing on my PC and you made it!!!!!!

[pcbheaven]

@dedasdude i am working also on a mind reading device and i read your mind :D xD

As a matter of fact, i will use this circuit for my coffee maker (maybe) and my PC (for sure) as well ! I'm glad you like it. I first designed it with a PIC, but i came to the conclusion (somehow) that: 1st it is an overkill, 2nd simple solutions should be given when possible and 3rd PICs tend to make me "lazy" and i should think analog once a while.
