4×4 Keypad Interfacing With Arduino Uno. To connect the 4×4 keypad to Arduino, you need to interface 4-row pins in the keypad which are (R1, R2, R3, R4) with the Arduino digital pins (9, 8, 7, 6), and the 4-column pins which are (C1, C2, C3, C4) with Arduino digital pins (5, 4, 3, 2). The picture down below shows the connection in detail.

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:
