Hello everyone, welcome to my new blog which is our Third project #3 (How To Connect LCD 16×2 Display To Arduino Uno). In this blog, we are going to connect an LCD display Using Arduino UNO. Display units play an important role in establishing good communication between the human and machine worlds. And so they are a big part of embedded systems. In this blog, I am going to explain only the connection or How to connect the LCD display to Arduino.
The 16×2 LCD will have a total of 32 characters 16 in 1st line and a further 16 in 2nd line. In 16×2 LCD there are 16 pins overall if there is a backlight, 14 pins if there is no backlight In each character there are 50 pixels.
- ARDUINO UNO
- power supply (5v)
- 100uF capacitor.
- Arduino IDE
- LiquidCrystal Library
Circuit connection of LCD Display To Arduino Uno:
Now let’s build the circuit. A circuit layout can be described in several ways. For this project ( How To Connect LCD 16×2 Display To Arduino ), we are using a physical layout diagram similar to the one shown in the above figure 2.
By comparing the wiring diagram with the sketched functions, You should start making sense of the circuit.
- LCD RS pin to digital pin 12
- LCD Enable pin to digital pin 11
- LCD D4 pin to digital pin 5
- LCD D5 pin to digital pin 4
- LCD D6 pin to digital pin 3
- LCD D7 pin to digital pin 2
- LCD R/W pin to ground
- LCD VSS pin to ground
- LCD VCC pin to 5V
- 10K resistor
- ends to +5V and ground
- wiper to LCD VO pin (pin 3)

In this blog, we understood how to connect the LCD screen to Arduino UNO. In the next blog, I will cover how to display text in an LCD screen using Arduino IDE.
