        • Identify the pins or contacts on the keypad module, typically labeled as ROW and COLUMN.
        • Connect the ROW pin of the keypad to a digital input pin of the microcontroller.
        • Connect the COLUMN pins of the keypad to digital output pins of the microcontroller.
        • Ensure the power supply for the keypad module is within the specified voltage range.
        • Write a program on the microcontroller to read the keypad inputs using the assigned digital pins.
        • Configure the microcontroller's internal pull-up resistors for the COLUMN pins if necessary.
        • Use the keypad module to input data or commands as required by your project.
        • Implement the necessary logic in your program to interpret and respond to the keypad inputs.
