This guide is for tinkerers and for those who want to do some fun with their Arduino board. Arduino is an open-source prototyping board which can help in making not only the garage door openers or home surveillance systems, but it can also help in creating some funny stuff in your home or office. Today, I will provide a tutorial on how to make LEDs flash to the music of an MP3 on your system. The flashing of LEDs will be based on the frequency of the playing MP3 music.
Let’s directly jump to the tutorial without any further ado.
There are four easy to follow steps to complete this Arduino Project. We will make a flashing circuit with attached LEDs and use an Arduino compatible music library and the Arduino IDE environment to analyze the frequency of music and give a response to different types of bits and blink LEDs accordingly.
To complete any Arduino Project, you will need some useful components at first to avoid any last moment inconvenience.
Things you will need for this Arduino Music LED Project are:
You have to make a small circuit design using Arduino, its accessories, and solderless breadboard to make the setup read music and blink LEDs in response.
As the inner rails and outer rails of the breadboard are connected through the lines, you can directly connect the components without messing with wires or using soldering iron.
Check these quick tips to create simple Arduino circuit:
The hardware part is done. Now, we will proceed to the software section.
Programming your development board for this Arduino music LEDs project is pretty simple. You just need to download and tweak with some coding scripts.
You can change the codes according to your needs and components you are using in this project.
Now, attach your MP3 player and speakers to the Arduino using audio jack and cables. Connect the power supply, check everything at last and that’s it. The Arduino setup will get the music input and change the LED lights accordingly.
You can even customize the script with the help of minim JavaSound Library of Arduino. Apart from analyzing the Arduino music signals, you can also do some cool things due to the Processing of this library.
You can extend the Arduino Music LEDs blinking from your table to your whole room with the help of resistors, capacitors, and drivers. Try using different ways of using LEDs and see which type of setup give you more entertainment. You can even try this Arduino project while throwing a birthday party for your friends and look at their reactions.
