Скачать или смотреть Arduino Reaction Time Game | Test Your Reflex Speed with LED & Buzzer

Test your reflexes with this fun Arduino Reaction Time Game! ⚡ When the LED lights up and the buzzer beeps, press the push button as fast as you can. Your reaction time is shown on the Serial Monitor — and if you beat your best score, you set a new high score! 🏆

This simple project uses an Arduino, LED, buzzer, and push button to measure how fast you can react. Perfect for beginners looking to improve their Arduino coding and electronics skills while having fun.

Components Used:
• Arduino Uno
• LED
• Buzzer
• Push button
• Resistors & jumper wires

Key Features:
✅ Measures your reaction time in milliseconds
✅ Displays score on Serial Monitor
✅ Simple and fun game to build
✅ Great beginner project for learning Arduino input & output

Try to beat your own reflex score! ⚡

ARDUINO CODE:

// Reaction Time Game with Buzzer + Best Score int ledPin = 8;
int buttonPin = 2;
int buzzerPin = 9;
unsigned long startTime;
unsigned long reactionTime;
unsigned long bestScore = 9999; // start with very high number
void setup() {
pinMode(ledPin, OUTPUT);
pinMode(buzzerPin, OUTPUT);
pinMode(buttonPin, INPUT_PULLUP); // internal pull-up Serial.begin(9600);
Serial.println("Reaction Time Game Ready!");
}
void loop() {
// Wait random time before LED on delay(random(2000, 5000));
// Turn LED ON + buzzer beep
digitalWrite(ledPin, HIGH);
tone(buzzerPin, 1000, 200); // 1kHz beep for 200ms startTime = millis();
// Wait for button press
while (digitalRead(buttonPin) == HIGH) {
// do nothing until pressed }
reactionTime = millis() - startTime; digitalWrite(ledPin, LOW);
// Check if new best score
if (reactionTime bestScore) {
bestScore = reactionTime;
Serial.print("New Best Score! Reaction Time: "); } else {
Serial.print("Reaction Time: "); }

Serial.print(reactionTime); Serial.println(" ms");
Serial.print("Best Score so far: "); Serial.print(bestScore); Serial.println(" ms");
delay(2000); // pause before next round }
