2. 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.

3. Design AC signal is inductively coupled to deliver power to carousel Power adapter is used with timer to create an AC signal All components above the inductive coupler will be housed inside the carousel

4. Functionality

5. Specifications Power Supply: 12 V, 3 A Width x Height: 14 in. x 14 in. Weight: 2.5 lbs prototype, 4.5 lbs finished Capacity: 16 4 oz. Jars (2 in. x 4 in.) Motor Torque: 3 Kg/cm Current Draw: ≈250 mA Stall Current: 3.7 A

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