| The system is built around the ATmega328P (XMini board). The user presses a button to advance through the letters D → A → R → I → U → S, each rendered as a bitmap pattern on the 8x8 LED matrix driven by a MAX7219. The LCD 1602 (I2C) shows the current letter being displayed. Two separate buttons increase or decrease LED brightness via the MAX7219 intensity register. | The system is built around the ATmega328P (XMini board).
