Full Wiring Diagram

NeoPixel Strip

• Circuit Playground VOUT --> NeoPixel +
• Circuit Playground G --> NeoPixel G
• Circuit Playground A1 --> NeoPixel DIN

Wire in your power terminal midway down your strip of LEDs for the most even distribution of power.

Speakers

• Circuit Playground VOUT --> Speaker POWER
• Circuit Playground G --> Speaker G
• Circuit Playground A0 --> Speaker SIGNAL

If you're using two speakers, plug the second into the first with your 3-pin STEMMA connector.

Capacitive Touch Board

• Circuit Playground 3.3V --> MPR121 POWER
• Circuit Playground G --> MPR121 G
• Circuit Playground SCL --> MPR121 SCL
• Circuit Playground SDA --> MPR121 SDA
• Pins 1-11 are connected to the capacitive touch pads on the bottles.

I also wired the additional G pin on the MPR121 directly into the power terminal G. The more grounding you can get, the better this board works.

Simple Lights-Only Wiring

If you don't care about the musical setup and just want to make a pretty light display, here's a simplified wiring diagram without all the fancy capacitive touch and sound elements.
