The Trinket M0 is the brain of this operation. The NeoPixel ring can be attached to any of the pins, but since the potentiometer is an analog input, it needs to be attached to pin 2, which is Analog 1 on the Trinket.

To reduce wire bulk, 5V and ground will be supplied to the potentiometer from the NeoPixel ring since the ring has two 5V and ground pins for daisy chaining.
