Introduction: Music Reactive Light||How to Make Super Simple Music Reactive Light for Making Desktop Awsome.

Hey whats up guys, Today we will build a very interesting project.Today we are gonna build music reactive light.The led will change its brightness according to the bass which is actually low-frequency audio signal. It is very simple to build.We will need a very few comportment for building this project.

Step 1: Parts List

Picture of Parts List

For building the project we need-

1.TIP31 Transistor
2.Led Strip

3.3.5ml Audio Jack

4.Prototype board.

5.3way switch

6.1 pcs dc socket and

7.2 pcs of dc connector

Step 2: Making the Circuit.

Picture of Making the Circuit.

Here is the diagram I have used.This is a pretty simple circuit.It takes around 20 minutes of soldering.I have used a 3-way switch for using two moods.One is making the light dance according to the bass another is continuously glowing the led strip.

Step 3: Connecting the Led Strip.

I measured the length of stip gonna need then cut it off after that I have used glue provided with the led strip for hooking it up with the monitor.Then soldered all the strip in Parallel. And connect it to the circuit.

Then I used hot glue to glue everything behind the monitor.

Step 4: Making the Power Source.

As a power source, I decided to use my monitor power supply instead of using an external power supply.So I made this power distributor socket for powering both my monitor and led strip at the same time, So I have built this power distributor.I soldered two dc connectors in one dc jack to built it.

Then checked if my circuit is working and it works like a charm.

Step 5: Testing IT!!

After connecting the audio jack to the pc Audio out It was working as expected..I changed the audio profile to bass mood and it certainly boosted the LED Strip brightness.... And we are all done :D

Thanks for reading.Hope you have liked my project...

Here is the VIDEO LINK to the project.

Please take a look at my youtube CHANNEL .

BYE BYE>>>HAVE A GREAT DAY.

You really need to add some base resistance 16-100 ohms to keep from frying your audio source. Right now its driving directly into a diode junction short( what the BE junction of an npn looks like as as currently hooked up as load )

Thanks bro for your suggestion.Means a lot to me .

Cool glad to help. I should sound better after if you crank it. Won't clip.
