Introduction: Arduino Interfacing With LCD Without Potentiometer

By My youtube channel
About: I like doing automation projects, 3d printing, and learning new engineering skills. Also at the same time, I believe in sharing whatever I learn with people around me and on the internet.

Aim: To interface 16x2 LCD with arduino without use of any potentiometer, breadboard, resistors

Components required:

1. Arduino Uno: https://www.dnatechindia.com/arduino_uno_r3.html

2. 16x2 Alphanumeric LCD: https://www.dnatechindia.com/Alphanumeric-LCD-2x1...

3. Jumper cables: https://www.dnatechindia.com/jumper-wire-male-to-...

Softwares required:

1. Arduino IDE

About this project:

In this project we will only be using a LCD, Arduino uno, jumper wires to display text on the LCD. We will use the digital pin 6 to control the contrast value of the LCD. The function to display text on the lcd will be | lcd.print (“Your text here”) |

Supplies

Components required:

1. Arduino Uno: https://www.dnatechindia.com/arduino_uno_r3.html 2. 16x2 Alphanumeric LCD: https://www.dnatechindia.com/Alphanumeric-LCD-2x16.html 3. Jumper cables: https://www.dnatechindia.com/jumper-wire-male-to-female-pack-of-40.html Softwares required: 1. Arduino IDE

Step 1: Procedure:

Connect the pins from the LCD on the Arduino digital according to the pins indicated in the table and schematic

Step 2: Code

1) Download the following code.

2) Open the following in Arduino ide.

3) Connect the arduino with your PC.

4) From the tools menu select the port and board correctly.

5) Hit the upload button and the text shall be displayed on your LCD.
