How to Scroll a single LCD line – Arduino
https://www.electronics-lab.com/scroll-single-lcd-line/
R Jordan Kreindler show us how to scroll a single line on a LCD display. The Liquid Crystal Library has two quite useful functions scrollDisplayLeft() and scrollDisplayRight(). These functions scroll the whole display. That is, they scroll both lines on a 1602 LCD and all four lines on a 2004 LCD. What we often need […]
