Since Halloween is just around the corner, I was thinking about using an Arduino to create music reactive lights. How should I go about wiring this? The LED strip I’m using takes 5V of power, and the music sensor also takes 3.3-5V. Should I wire the battery straight to the LEDs, or to the Arduino?
I’ll link the two below:

Use a power supply like this to power your project.
5V 5 Amp power supply
The problem is, I’m going to be wearing it on my body. It’s going to be on a hat.
Also where should I connect it?

Then there are a great many 5v power banks you can use.
You need to get your amp hour to match your expected use time.
5v Power Bank
Thanks! Question: do you think just a 9V battery would be enough?
Alright. Do you know of anything cheaper by any chance?

The internet is your friend.
Thanks for your help!

Be scared, be very scared of dark places on Sunday October 31 !
That’s why I’m creating these lights!
One more question, I’ll just send the power directly to the Arduino Uno, right? And then the led strip and the sound sensor will take from there?
I found a power supply, by the way.

You would have 3 wires connected to each supply lead, i.e. +5v and GND power Bank terminals.
The Arduino 5v pin goes to one of the +5v Bank wires.
NOTE: Do not connect an UNO or Pro Mini to the Bank when you upload your sketch to the Arduino from the PC.
What Arduino are you using ?
So it doesn’t go to vin, right?

Vin requires 7 to 9v (12v if you are careful).
The 5v pin is your connection point for the 5v Power Bank.
NOTE: Do not connect an UNO or Pro Mini to the Bank
when you upload your sketch to the Arduino from the PC.
That’s what I thought. Thanks again!
