its a RGB LED STRIP ORGAN and don't used any microcontroller. its based N-channel mosfet.

6) Diode - 1N4148 -1ps

7) 50K ohm Potentiometer- 1ps

8) Transistors
I) 2N3904 - 1ps
II) 2N3906 - 3ps

9) LED
I) Red Led- 1ps
II) Green Led- 1ps
III) Blue Led- 1ps

10) Capacitors
I) 10uF electrolytic-1ps
II) 0.047uF ceramic- 1ps
III) 0.47uF electrolytic- 1ps
IV) 0.01uF ceramic- 1ps
V) 1uF electrolytic- 1ps

11) Resistors

I) 100 ohm - 2ps

II) 10K ohm- 2ps

III) 1k ohm- 1ps

IV) 2.2K ohm -3ps

V) 4.7K ohm- 2ps

VI) 150 ohm -1ps

VII) 270 ohm- 2ps

Step 2: Circuit Diagram

its a very simple circuit, I found a circuit for total 6 LEDs on the internet. I took is and modified it to drive full 5 meters RGB LED STRIP by using the N channel mosfet, here is the Circuit diagram take a look

Step 3: Video

Hear it is in the working I have a you tube channel by the name of ELECTRONIC JUGAAD plz check it out.

and if u have any question plz comment below I will answer them as soon as possible.

<p>This looks so cool! I'd love to see this turned into a EL wire suit for raves! That would be awesome!</p>
<p>yes that will be awesome I will try for it soon!</p>
Thanks for publishing this. Everyone seems to think you need an Arduino to make a light blink these days. This proves otherwise!
<p>thanks for writing, plz share this. and share your build with me</p>
<p>I've made this circuit twice now and think it's fantastic! Here's my second take on the circuit, I recently incorporated it into another project of mine: <a href="https://www.instructables.com/id/RGB-LED-Strip-With-Dimmers-on-RGB-Lines-and-Colour/">https://www.instructables.com/id/RGB-LED-Strip-With...</a> where I was really pressed for space. Whilst the circuit diagram in your Instructable seems to have a lot of components, I thought I would share my pictures to show that if you're smart with your layout then it can, in fact be quite compact! </p>
<p>I added 50K pots at the output on every color (RGB) to attenuate the amount of color in the strip.<br>The result is awesome! <br>Thanks for sharing</p>
<p>video test:<br>https://www.youtube.com/watch?v=Kk90hwyu-CU</p>
<p>didnt had mosfet so i use tip31c and reverse it after rgb led (didnt notice before that rgb led has 1 common + and 3 - for each color</p><p>https://www.youtube.com/watch?v=rwskswdi4tA</p>
<p>any clue?</p>
<p>could you explain how to use a tip31 in this circuit in more detail?<br>thanks</p>
<p>Wow!! This looks awesome!</p><p>I totally want to make it. I have one small question though, what do i do to connect leds (say 5 leds for the 3 frequencies) instead of the led strip?</p>
<p>WOW!! Looks so awesome!</p><p>Nice work, dada.</p><p>I have one question though. What if I want to use led's (say 5 leds for each color), how should I progress??</p>
<p>I believe you introduced an error in your diagram. You have an additional join where the 10uF, 10K Ohm, 1N4148, and 2N3904 components are. The original drawing over at http://makezine.com/projects/easy-led-color-organ/ doesn't have this join.</p>
<p>hi I am trying to replicate your project i have some questions, 1 is the 10K at the base of 2n3904 looks shorted 2, what is the use of the mosfet?</p>
<p>here's mine</p><p>https://www.youtube.com/watch?v=xnMQG-hF-ho</p>

<p>I built mine, just a little adjustment on the circuit above. <br><br>https://www.youtube.com/watch?v=xnMQG-hF-ho</p>
<p>Hello, I was wondering if you could tell me how to hook this up to an alternate power source, such as the fuse box/car battery of an automobile?</p>
<p>its simple if u have 12V battery in your car then hook car battery ground to circuit ground and connect positive to circuit's positive and put an on/off switch between it. </p>
<p>i am confuse what is male header sv1 on the top for?</p>
<p>thats for RGB strip output.</p>
<p>hi,</p><p>im working on the same thing only i want that i can still use al the colors of my rgb led strip. So i can ir remote the color and it will jump with it on the music. Until know not mutch succes. Im just useing transistor's, driver and adapter, and a +12V 3A remote then (adapter the same specs) the strip is 4m long, and 4 wire's (afcorse) and if i possibly can then i want to have a switch between so i can turn it off - flashing on sound - normal on </p><p>I hope to hear from you!</p>
<p>I think it will not work but u can do one thing place IR controller on the one end of the strip and the other end place this COLOR ORGAN Circuit but use only one at a time u can do this by using center off toggle switch by this only one Circuit will work u should use 2 separate power supply. when u use the COLOR ORGAN Circuit u may see some deference in the colours. ur u can buy Music sensitive controller remote key IR for rgb strip. write again if u have any question.</p>
