Reaction Test: The Arduino Reflex Game

Who has the fastest fingers? The Simple Reflex Game is an addictive arcade-style project that uses a sweeping row of LEDs to test human reaction speed. It is a fantastic exercise in time-critical programming.

The Core Mechanic

  1. The Display: A row of 5 or 10 LEDs. The middle LED is the "Target" (usually a different color, like green).
  2. The Sweep: The LEDs flash sequentially back and forth, like a Cylon eye or KITT from Knight Rider.
  3. The Input: The player has one Push Button.
  4. The Goal: The player must press the button at the exact millisecond the green "Target" LED is lit.
  5. The Logic: If digitalRead(button) == HIGH while current_LED == Target_LED, the player scores a point.

Hardware Elements

  • Arduino Uno/Nano: The game engine.
  • LEDs (Multiple Colors): 4 Red, 1 Green (for the target).
  • Push Button: The trigger.
  • Piezo Buzzer: For "Success" ding and "Fail" buzz sounds.

The Challenge Factor

As the player's score increases, the delay() between the LED shifts gets smaller, making the sweep move faster and fast. This teaches you how to use dynamic variables to change the difficulty Curve of a software program on the fly.
