In this engaging show-and-tell, Aaditya demonstrates a Reaction Speed Game built using an Arduino, LCD screen, LED, buzzer, and a button. The game challenges players to react quickly after a random delay. The LCD shows instructions and feedback, while the LED signals when the reaction window begins. A buzzer gives sound feedback depending on how fast the player responds. The system calculates reaction time in milliseconds and updates the score accordingly. Aaditya walks through the code, explaining how variables, conditional statements, and timing functions control game flow. The game is fun, educational, and endlessly repeatable.
Aaditya kicked off his show-and-tell with an exciting project: a Reaction Speed Game. Built using an Arduino, the setup included an LED, an LCD display, a buzzer, and a button—each component playing a vital role in testing and scoring reaction times.
He explained the game’s flow: the LCD first displays “Ready.” When the player presses the button, it says “Wait for it,” then after a random pause, “Press now!” That’s when the timer starts. The player must hit the button as quickly as possible, and the game calculates the reaction time in milliseconds.
Aaditya showcased how the LED signals the start of the reaction window, while the buzzer gives different sounds based on speed. The LCD displays the time taken and rates the player’s performance as “Instant,” “Fast,” or “Too Slow.” Points are awarded based on speed, and the score updates in real time.
He also did a live demo where each press showed changing outcomes, proving his code’s accuracy. Aaditya carefully explained his use of variables, the millis() function for time tracking, and conditionals to judge and score speed. His project was both fun and educational—a perfect example of how coding and electronics can come together in a cool, interactive game.
