This project demonstrates basic SPI (Serial Peripheral Interface) communication using an Arduino UNO as the Master device. It sends a sequence of 8-bit data values (0x80 → 0x01) through the SPI bus — a useful experiment for testing data shifting, LED control through SPI, or communication with SPI-based peripherals.
