🔌 Arduino Code / Setup

Run this code on an Arduino Mega 2560 board in the Arduino IDE

Here is a list of the events on the hardware:

• Waiting for game mode selection: RGB lights up cyan, and red, yellow and green LEDs light up
• Game mode selected: RGB lights up magenta
• Game counts down: Red, yellow and green LED lights up one by one
• Game is ready: White LED lights up, a sound cue will indicate the start of the game
• Game ends: RGB lights up blue

📊 Leaderboard

The leaderboard displays the top 10 reaction times. It updates in real-time as new scores are added.
