From Fiction to Functionality I watched a Netflix movie that stuck with me — Brick, a sci-fi thriller where the residents of an apartment building are cut off from the outside world by a mysterious, seemingly indestructible

Introduction This Arduino-based project transforms a handful of LEDs, buttons, and a digital display into an interactive experience that tests the player’s focus and reaction speed. The game begins simply: a pulsing red LED waits for the player to press the start button. A countdown follows, and once it ends, the player enters a series of levels with increasing difficulty. At each level, the LEDs flash in a rapid sequence,

Introduction Color Clash is a fast-paced, interactive game built with Arduino that blends LEDs, buttons, and a TM1637 four-digit display into a challenge of focus, pattern recognition, and quick decision-making. The experience begins with a pulsing red LED, signaling the player to start. A countdown sequence—complete with sound effects—sets the mood, and the player is launched into a series of increasingly intense levels. In each round, colored LEDs flash in
