Arduino Vumeter With 6 Operational Modes

About: I'm an electronic engineer and i love to learn new stuff and also share my knowledges with everybody and make tutorials to teach about the things that i make.

Intro: Arduino Vumeter With 6 Operational Modes

Hello fellas, this is my first instructable, and yeah, i know it's not a full step by step, but i will show you in a general way how to make a Vumeter using Arduino and plus it has 6 different modes of operation as you can see in the video.

Step 1: Materials

What you need in order to do it is:

1. An Arduino UNO Board.

2. At least 10 LED's.

3. 1k Resistors.x 11

4. Some wires.

5. Push button (Normally Open).x 1

6. 3.5mm Audio Stereo plug x 1.

Step 2: The Diagram Connections

Just follow the diagram connections that i post in this step and you will be ready to go, you shouldn't need anything else, just plug your Arduino to your pc, and the audio jack to your pc audio output or your phone, and play the music to see the magic happens. For chaging the mode you just press the push button and it will change from one mode to another. You can dispose the led's inside anything you want or just let them free, in my case i made an acrylic tower and put the led's inside of it..

Step 3: The Arduino Code

This is the code for Arduino that will make your Vumeter work, once you have all the connections mentioned on the previous step, you just have to plug your Arduino into your PC and upload the code that i post you for downloading in the following link.

And that's all folks, if you have any doubt you can let me your comments below and i will be happy to help you.

Happy coding.

    Hey, glad you like the video, and which song do you refer to? All of the songs are from soundtrack of the game Bloody Roar 2 from PS1.
