• Bright white LEDs
• 3D printed parts, will release later

Install the camera in to the ribbon cable slot on the Raspberry Pi board.
Wire up the limit switch to the respective pin you chose in core.py.
Wire up the stepper motor to the motor driver.
Wire the motor driver to the respective pins for the motor phases in core.py.
Wire the white LEDs to the pin you chose in core.py.
Place a platform on top of the limit switch.
Mount the camera above the platform facing downward.
Place the food bowl in the food shelf and position in front of platform.
