LCD Hacks You Must Know | Arduino 16X2 LCD Module
@TechnoVillage2024 In this video we have tried to use different commands play with the LCD 16X2 module. You can precisely place the characters at any place you want. You can print 2 lines, you can print single line, you can change Cursor styles, even stop displaying the cursor.
