HANDS-ON PROJECT


                  PROJECT NAME: Emoji Project

                  Objective:

                  You will:
                  Design an interactive  Emoji  Project  using  speech  recognition  and servomotors.  This project

                  involves converting spoken commands into mechanical movements, enabling an emoji face to
                  express different emotions by adjusting facial components.
                  Creating an Emoji Expression

                     Idea: Use one servo for the mouth, two for eyebrow or eye movement.

                     Mounting: Cardboard or 3D-printed face with servo horns attached to mouth or brow pieces.

                  High-Level Workflow
                     Microphone: AI software (PC or online) interprets the voice.

                     Recognized Command (“HAPPY,” “SAD,” “NEUTRAL,” etc.) is sent to Arduino.

                     Arduino sets servo angles to depict the corresponding emoji expression (e.g., smile mouth for
                     “HAPPY”).

                  Components Required

                  Materials List:
                     Arduino Uno – Microcontroller for processing voice inputs.

                     Servo Motors – To control emoji facial expressions.

                     Microphone – Captures voice commands.
                     Power Supply & Jumper Wires – For connections.
