Creating Tetris Game with Arduino and OLED Display

This portable Tetris game is built around an Arduino Nano microcontroller that coordinates game logic, player input, and visual and audio output. The system runs on a 9V battery, supplying power to the Arduino. A 128x64 I2C OLED display serves as the visual interface, communicating with the microcontroller via the Wire, Adafruit_GFX, and Adafruit_SSD1306 software libraries to render falling tetrominoes and the game grid. Player control is handled by four push buttons wired to the breadboard and connected to digital pins on the Arduino Nano, allowing the user to move pieces left, right, rotate, or drop them faster. As the game processes input and updates block positions on the screen, a buzzer provides retro sound effects and audio feedback for actions like clearing lines or dropping blocks. The entire circuit is prototyped using a breadboard and jumper wires to securely link the components together.
