Arduino Reaction Time Test with Sound Cue

Arduino Reaction Test Station This project is a digital test setup developed to measure a user's reflex speed to visual and auditory stimuli with millisecond (ms) precision. The system consists of an Arduino controller, a three-stage LED notification group, a buzzer for audible warning and an I2C LCD display that shows the results instantaneously. Working Principle: When the test starts, the system prepares the user by lighting the red and yellow LEDs respectively. After a randomly determined p
