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.
Circuit Design: Connecting Servo Motors to Arduino
Connections Overview:
Component Arduino Pin
Servo Motor (Mouth) Pin 9
Servo Motor (Eyes) Pin 10
Servo Motor (Eyebrows) Pin 11
Microphone Module Analog Pin A0
