LCD DISPLAY USING WITH I2C FOR ARDUINO
I2C LCD DISPLAY A liquid-crystal display is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector to produce images in color or monochrome. Using an I2C interface to connect an LCD to an Arduino is a more efficient way of wiring, as it reduces the number of pins required. Below are the steps and code needed to set up and use an I2C LCD with an Arduino. Components Needed: 1. Arduino Board (e.g., Arduino Uno) 2. 16x2 I2C LCD Display (or a standard 16x2 LCD with an I2C backpack) 3. Breadboard 4. Jumper Wires Steps to Connect the I2C LCD Display: 1. Wiring: - GND → Arduino Ground (GND) - VCC → Arduino 5V - SDA → Arduino A4 (for Arduino Uno) - SCL → Arduino A5 (for Arduino Uno) Note: On different Arduino boards, SDA and SCL mi...
