Introduction to Arduino & Sensor Integration

Before diving into complex embedded systems, I attended a hands-on introductory session focused on microcontrollers and sensors. We were provided with original Arduino boards, breadboards, IR sensors, and LEDs to learn the fundamentals of circuit building and hardware integration.

• Understood digital and analog pin configurations on the Arduino.
• Wired an IR sensor to control a red LED, observing the sensor's blue indicator glow on light surfaces and the red LED glow on dark surfaces.
• Gained practical experience bridging code with physical hardware components on a breadboard.

Arduino-Based Tic Tac Toe System

System Overview

Built an interactive 2-player game using Arduino Uno. Integrated LEDs, joystick, push button, and buzzer.

Outcome

Developed a complete embedded system combining hardware control and real-time game logic.
