ReactionTimeGameArduino

This Arduino project tests a player's reaction time. When the LED lights up, the player must press the button as quickly as possible. The reaction time is displayed on the 16x2 LCD screen.

How to Play

1. Upload the code to your Arduino board.
   
2. When "Get Ready..." appears, wait for the LED to light up.
   
3. Press the button as quickly as possible when the LED lights up.
   
4. Your reaction time is displayed on the LCD.
   

Components Needed

• Arduino Uno
• 16x2 LCD Display (with I2C module)
• LED (any color)
• Push button
• 220-ohm resistor
• Breadboard
• Jumper wires

Wiring Instructions

1. Connect the LED:
   • LED anode (long leg) to Arduino pin 8 via a 220-ohm resistor
   • LED cathode (short leg) to GND
2. Connect the push button:
   • One leg of the button to Arduino pin 7
   • The other leg to GND
   • Use the internal pull-up resistor in the code (no external resistor needed)
3. Connect the LCD:
   • VCC to 5V
   • GND to GND
   • SDA to A4
   • SCL to A5
