If you do as he says in the video, your circuit will work, trust me. I tried and it works perfectly. I didn't change anything. At the end, don't forget to put the volume at maximum, it is important that you do it if not, the LEDs will not light up.

I just finished the last stage of this project and it works great. just listen and follow the directions. FANTASTIC! Thank you! had alot of fun and learned something!!!!!!

Can we have Collin's Lab back?

Hey, I followed the instruction strictly and all the components are right. The led color organ "blinks" like a charm

i just completed the amp stage, high stage and mid stage using the diagram listed above and follow the vocal out line, however i have changed the 1k to a 1.5k resistor. Works great so far with no complaints! don't follow the advise listed below. It's wrong. start in the first and second part of the diagram, then build the mid and low end if your a beginner. like i am. you'll love this project. btw get a branch for speakers otherwise you only see flashing lights no music off your cell phone. nice little project of 10 bucks.

i have build a one , working just fine , thank you !!!

Hey Great Video!.. Actually i was making one but having a problem deciding the amplification factor!..i mean the Vmax varies with the whole song! So how do i decide the exact voltage amplification??!

Everything in the schematics is right. We had to modify two points: (1) in the section with the red LEDs, take out the 2.2k resistor connected to the capacitor and move the jumper directly to the capacitor. (2) Also in the section with the red LEDs replace the 2N3906 with a 2N3904 transistor.

You can also add another aux port on the same row as the previous one if you dont have split aux cable this allows you to speakers or head phones without it !

That was great, thx !

you have a pnp symbol for the 2n3904.

Would you consider this project suitable for a novice in electronics? And if someone would explain what the first part of the circuit does before the filters and right after the audio left and right inputs.

Brilliant ending.

Would be possible to sting up some sewable LEDs in parallel and create a light up coat that plays music and flashes to the beat. If so please help me with this.

Can I wire a strip of less in replace of the single led's itcomes with?

I can only get it to work when the battery connection is "barley" touching, it doesn't work when its completely within the circuit...any suggestions?

Does any one know that what is the background song playing on ?

Is there a way to miniaturize this design using SMD components running on 3V?

Maybe, but you need to fine tune all the resistors and wire the LEDs in parallel of two directly between the transistors' collectors and ground.

Hey I want to make the same project using LED strip (powered by 9V adaptor) please tell me how can I modify the circuit? thanx in advance

You will need a common anode RGB LED strip and a 12 volt power supply. You will need to remove the six LEDs and their resistors from the circuit and get either a P-channel MOSFET with pullup resistors, or use a PNP power transistors and wire them in place of the LED pairs you removed. Remember to use a pullup resistor for the MOSFETs, or base resistors for the power transistors.

Hi I want to make an stage light effect with 5x5 led matrix with aurdino

If you were to play a larger resistor and then a transistor in between the two series LED's, could you make the second LED only flash during large periods of frequency use

Just a few questions. I'm planning on building this for my home theater system hooked up to a receiver. 1: is there a way to connect this between my receiver and my speakers? 2 I'm looking to use 5M led light strip for each color. Could you help me by making a video on how to do it with the strips on a breadboard but still be responsive to the music? Hope you can help. Thanks

take it off your tape monitor output from your receiver, works great!

The schematic in the video has different transistors than in the PDF. In the PDF, it says Q1 is supposed to be a 2N2222A, in the video it's 2N3904. In the PDF, Q2-4 are 2N2907A, and in the video it's 2N3906. Are these equivalent?

Make should consider sharing the music in this video as well :)

is it real, give music for LED from usb port?

make npn transistor circuit please

Can we still have Collins Lab?

just a few things need to be modified. for certain breadboard, we need to use jumpers on the leftmost and the rightmost panel in the middle because certain breadboard is not connected. secondly, u need to use an amplifier because the power from your phone is insufficient, or you can use a laptop or pc. btw fun project.

I followed the instructions carefully but the blue LED's (high frequency) is on even without music and it is the only one lighting up. Also the blue LED's is responding on low frequency sound when i played a music, not on high frequency. What do you think is the problem there sir? thanks.

Anglais I don't understand the fourth resistor in the circuit ((10k), it must not be in its place because it is useless because it is in short circuit?

can we increase the number of led or how can we increase the amount of blinking light? it will more fun!!!

@PunakiviAddikti

Yes, but the pinout is different. You need to look at the pinout of BC547 and wire the gate, drain and source to the correct points in the circuit, you can't just swap them in.

Cool

it didn't work with most people because the wiring is wrong with the 2n3904 and it said 2n3906 in the schematic and here he uses the 2n3904 it's an npn transistor and he draw it 2n3906 as a pnp transistor

ههههههه بتاع اللمض ... good work

HEY! Your audio input transistor is labeled as a 2N3904, which is an NPN transistor, but you show a 2N3906 transistor in that location. I hope you've already rectified that mistake.

instead of triggering 3 leds at 3 different frequencies, couldnt you trigger 3 relays instead. i was thinking christmas lights. thats like 100leds.x 3

@TheKeyboardist89

4 жыл бұрын

I would stay away from relays as they have a slow response and have contact bounce. Moreover, the transients might damage your Christmas lights. I would instead use TRIACs which give a "cleaner" switch and can respond faster.

it's nothing to look at. I'd much prefer something that requires soldering and is less flimsy looking. Plus, I associate deeper colors with deeper sounds, so red and bass seems like a conflict of interest.
