LCD 16x02 Connection:
The Arduino's +5V and GND will be connected to the pin of the breadboard
The LCD has 16 pins and the first one from left to right is the Ground (GND) pin
The second pin is the VCC which we connect the +5V pin on the breadboard.
Next is the Vo pin on which we can attach a potentiometer for the contrast of the display
The RS pin will be connected to the A0 pin of the Arduino.
The RW pin will be connected to the GND pin of the breadboard.
The E pin will be connected to the A1 pin of the Arduino.

Keypad 4x4 Connections:
The keypad has 8 pins, 4 of them are for the rows and other 4 pin for the columns.
The keypad I'm using is 4x4. It has an additional connection input. The keypad used in the circuit diagram is 3x4.
The Keypad's pins will be connected respectively to the Digital 1-2-3-4-5-6-7-8 pin of the Arduino.
