Connecting 16x4 LCD with Arduino

In this step-by-step tutorial, I’ll show you how to connect a 16x4 LCD display to an Arduino Uno and make it display custom text, numbers, and even scrolling messages! Whether you're a beginner or an experienced maker, this guide covers everything from wiring to troubleshooting common issues (like blank screens or solid blocks).

🔌 What You’ll Learn:
✔️ Correct wiring for 4-bit mode (fewer pins needed!)
✔️ How to adjust contrast (fixing blank/blocky screens)
✔️ Upload & test Arduino code (with explanations)
✔️ Troubleshooting tips (if your LCD doesn’t work)
