Arduino LCD Character Display Tutorial | 16x2 LCD with I2C Adapter
Add a text display to your Arduino projects with a 16×2 or 20×4 LCD character display. This tutorial covers both direct wiring (4-bit mode) and the popular I2C backpack adapter — reducing 6 wires to just 2 — using the LiquidCrystal_I2C library.
📺 What you'll learn and more topics to research:
• How LCD character displays work (HD44780 controller)
• Direct 4-bit wiring to Arduino
• Using an I2C backpack to reduce wiring to 2 wires
• LiquidCrystal and LiquidCrystal_I2C library usage
• Displaying text, custom characters, and scrolling messages
