Story

The project is about how to control the music volume and visualize the volume level on a led bar in an easy way by using the amazing 1Sheeld.

1Sheeld turns your smart phone into more than 40 different Arduino shields so it's saves a lot of money and gives you the ability to make great projects and it's available at both android studio and apple store.

You can check all 1Sheeld's tutorials which will take you from the early beginning into more and more advanced projects from that link. http://1sheeld.com/tutorials/

And you can order it from here

All the details of how it works will be in the video uploaded and you can find the hardware connections in the schematic.
