Introduction:

Music reactive LED Strips are great for lighting projects. You can make this with Arduino and also without Arduino. In this article, we are going to discuss how to make Music Reactive LED Strip by using Arduino Programming. The code is a simple working process is also simple. You just need to understand the working principle.

Schematics of Music Reactive LED Strip:

How does the Music reactive LED Strip circuit work?

This is an easyMicrocontrollerbased project. The microcontroller gives a signal to the connected Transistor's Base and it drives an N-Channel MOSFET. And this MOSFET drives the higher loads like LED strips.

Now let's talk about how the signal is generated from the microcontroller. At first, the Audio sensor's out pin gives a signal. Then it is taken through Arduino. If the signal is in a certain limit then only the led strip will run.

If the Condenser mic didn't get a signal then the sensor module doesn't give output. So, in this case, the LED strip will not run.

This process repeats over and over.
