Interfacing 4x4 Keypad with Arduino
First, connect the 4X4 keypad to the Arduino; connect the first six pins on the 4X4 keypad with the A0 and A5 pins on the Arduino. Then connect the last two pins on the 4X4 keypad module to digital pins 3 and 2 on the Arduino. After that, connect the LCD to the Arduino. The connections for connecting the LCD with the Arduino are as follows:
