Arduino Interfacing With LCD Without Potentiometer

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”) |
