Music BEATS is awesome and LED lights attract our attention. Lets see the effect when both Music BEATS and LED lights are patched up together.... (Y)

Step 1: What You Will Need

1) 5m LED strip (one or two as you wish)

2) Adapter < 240V input and 12V output> (one piece)

3) Breadboard(one piece) with some wires for connection

4) 3.5mm Y splitter jack i.e with one male and two female points (one piece)

5) One 3.5mm jack (with one wire to ground and one wire to left or right)

6) Diodes IN4007S (2 pieces)

7) 100K ohm resistor (2 pieces) , 1K ohm resistor (1 piece) , 5.1K ohm resisor(1 piece)

8) LM324N Quad opamp (1 piece)

9) TIP31C transistors or TIP41C (1 piece)

Note1: If you have taken 2 or more led strips then you need to connect parallel to the first led strip.

Note2: Take either TIP31C or TIP41C (here TIP 31C is used)

Step 2: Use of Adapter

The Adapter must be correctly rated as discussed before.

Higher output value can burn the circuit.

-ve part of 12V output will go to the ground of the circuit.

+ve part will go to the 4th pin of the LM324N and to the +ve of the 5m LED strip.

Step 3: 3.5mm Y Splitter Jack and 3.5mm Jack

The Y splitter will have one input from the circuit

and one input fromm the speaker. The 3.5mm jack of Y splitter will be placed in the mobile or laptop.

The 3.5mm jack will have open end with one wire for ground and other for left or right connected to the circuit.

It is clearly shown in the following circuit diagram.

Step 4: Circuit Diagram

This free hand circuit diagram shows everything clearly.

Keeping in mind the previous points,

follow the circuit on your breadboard and its done..... (Y)

Step 5: On Completion It Will Look and WORK Like This

Step 6: PCB View

Once completed, you can draw the same circuit on a small PCB so as to fix it permanently.

This pic is one of its view.

It will require some sort of soldering. But this is the last part.

It would be better to focus on a breadboard as a beginner

Thanks...

<p>I can't make this work. I connect everything and the led strip is at a 50% but has no changes with the music. I don't know what can be the problem. The resistor in the right are for a amplify in 20 the signal, but what's the reason of the resistor in the left?</p>
Hi.. I see four wires from the adapter.. 3 red and one black.. but not sure where to connect which.. could you please help me? <br>p.s: m a newbie :p
<p>Two red wires coming out from 240v input must go to the power socket </p><p>and....</p><p>-ve part(black) of 12V output will go to the ground of the circuit.</p><p>+ve part(another red) will go to the 4th pin of the LM324N and to the +ve of the 5m LED strip.</p>
<p>Thank you :) I just had my package arriving from Amazon when i remembered that i ordered RGB lights. So, that creates a problem coz i have 4 wires coming from the adapter (red,blue,green and black) unlike the traditional adapter, and i am not sure which two are output and which two are input. i'll upload a pic. Could you please help me? Does the same circuit apply to RGB LED strip as well?</p><p>This is a Beautiful project and Thank you for sharing it with us.</p>
<p>ya its really a beautiful project..... u can try.... (Y)</p><p>It looks awesome...... (Y)</p>
<p>Nice one bhai ! i too have done this many years back. I have few questions though.</p><p>1. Is the op amp you used available in market ?</p><p>2. Are you able to filter sound with low,mid,high from what i see they are not. Are you planning to i would love to see the enhancement.<br><br>3. Why do you use so many diodes and resistors (I know basic electronics) from what i could see you are giving 12v to strip and there is no reason it will fry the LEDs<br><br><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/Lp6g3PDeM4E" width="500"></iframe></p>
<p>That op amp is available in plenty in market..... and building a circuit for filtering the frequencies is really a big one than this... At present i am not working on filtering the frequencies, later in future if possible i would definately try to have a filtered circuit..... ;)</p>
What changes would you make?<br>I plan on doing this myself and would like your input.
<p>See the thing is all light beats on same i/p sound. They turn up exactly the same. There should be filter in between wherein the sound is filtered based on High-Mid-Low 's and the effect way par than this.<br><br>But filtering sound takes a lot of overhead. If i was doing this i would not use a sound splitter and audio jack i would rather use a mic since all lights on same frequency.<br><br>I have tried mixing the left only, right only and left+right channels but they are close almost same.</p>
Great idea, but can you upload a video or a link to one?<br>I'd love to see it in action
<p>Here is the link.....</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/RPwxzCv50t0" width="500"></iframe></p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/nYsL-1NuteM" width="500"></iframe></p>
That is awesome!!
<p>Great project but i was curious as to where got the adapter from?</p>
<p>We get that adapter and led strip together or separate in any electronic store...</p>
<p>OMG thanks dude!</p>
