Wired Connections

DC Motor

• GND from motor to MOTOR 1 pin 
• VCC from motoro to MOTOR ground pin

NeoPixel

• DIN from NeoPixel to NeoPixel DIN on CRICKIT
• 5V from NeoPixel to NeoPixel 5V on CRICKIT
• GND from NeoPixel GND to NeoPixel GND on CRICKIT

Photo Interrupter

• VCC (+) from sensor to 3.3V on CRICKIT
• L from sensor to 3.3V on CRICKIT
• GND (-) from sensor to GND on CRICKIT
• OUT from sensor to Signal 1 on CRICKIT

Powering

The Feather and CRICKIT FeatherWing can be powered using a single 5V power supply.

A 5V 2A power supply connects to the DC jack on the CRICKIT board. In this project, an adjustable power supply is used.
