Simon Game - Arduino Memory Game
We are making the classic Simon memory game with Arduino! A fun memory game project using 4 LEDs, 4 buttons, piezo speaker and I2C LCD display. The game randomly generates a sequence of LEDs and the p
Arduino I2C Calculator
It is an Arduino-based calculator project that performs addition, subtraction, multiplication and division operations using a 4x4 membrane keypad and a 16x2 I2C LCD display. Thanks to I2C, the display connection is provided with only 2 cables, thus reducing cable clutter and keeping more pins open for use. There is also decimal number input and negative number support.
Arduino Sound Stimulated Reaction Test
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
Arduino Roulette Wheel
Electronic Roulette Wheel with Arduino This project is an Arduino-based electronic game setup that simulates the factor of chance with a digital algorithm. The system creates a "wheel" mechanism with LEDs arranged in a circular line, flashing sequentially and rapidly. Working Principle: When the button is pressed, the cycle starts at a high speed and gradually slows down towards the target point determined by the random number generation function (randomSeed) in the software. The speed at which
Arduino LCD Runner Game
Side scrolling endless runner game running on 6x2 character LCD screen. Hero runs automatically, player jumps over obstacles by pressing the button. Random obstacles appear on the top and bottom row. Passive buzzer plays opening melody, jumping sound, 50 point celebration sound and end of game melody. "BlueGrays - Arduino Projects" splash screen is shown on startup. The score is updated instantly in the upper right corner of the screen.
