Introduction
Problem Statement: To build a spice rack that will use voice/speech recognition to locate the correct item. Once identified, the carousel will rotate, bringing the desired spice to the front, and illuminate the ingredient with a LED for quick visual identification.Slide3
Design
AC signal is inductively coupled to deliver power to carouselPower adapter is used with timer to create an AC signalAll components above the inductive coupler will be housed inside the carouselSlide4
FunctionalitySlide5

Testing Plan
Rectified Inductive Coupler - Test rectifier output with coupler attached. Need 12 VDC, 0.75 A output to supply motor and microprocessorRotational Movement – Use voice commands to rotate the motor clockwise and counterclockwise until specified hall effect sensor is recognizedJar Identification System – Test ability to identify different voltage drops, representing different jars of spiceSlide9
