There are three wires we need to attach: red for power, black for ground, and yellow (or sometimes white) for data. 

• Red goes from VOUT to +5V
• Black goes from GND to GND
• Yellow goes from A1 to DIN

You can plug a battery pack into the battery connector, or plug into the USB port to power your project. 

Note: A0 is connected to the speaker, so we suggest using the other pads that are free, like A1.
