Bluetooth Speaker with Music Visualizer

In this video, I'll show you how I build this Bluetooth Speaker which has a music visualizer at the top. It looks really cool and makes the song listening experience more awesome. You can decide whether you want to turn on the visualizer or not to save battery life and consequently get a longer play time.

[@austin8415]

im doing this project, but i have one question after you soldered the 5v wire to the switch, what device did you solder the ground wire to?

[@Tesalex]

Solder the ground wire to Bluetooth module and Arduino as well.

[@Tesalex]

Let me know if it's clear to you, or I'll try to make you understand in a different way.

[@PatchworxStudios]

Hmhh maybe you should consider another project first... Ground wire goes to common ground.
