| The 4x4 Keypad is connected using a matrix scanning technique, utilizing 8 digital pins to minimize I/O usage. The Passive Buzzer is connected in series to the MCU to prevent overcurrent damage to the digital pin. The Slide Potentiometer acts as a voltage divider, providing a linear voltage between 0V and 5V to the ADC (Analog-to-Digital Converter) on pin A0. | The 4x4 Keypad is connected using a matrix scanning technique, utilizing 8 digital pins to minimize I/O usage.
