Not My Project
I took a classic Arduino 16×2 LCD display and rebuilt it as a giant 7× larger version using 840 addressable LEDs.
Instead of trying to manufacture a real liquid crystal display, I replaced every LCD pixel with an individually controllable LED and designed custom PCBs to recreate the original 16×2 layout.
The goal was not only to make a huge display, but also to make it compatible with the familiar LiquidCrystal_I2C Arduino library. Using a custom interceptor board, the giant display can understand the same commands as a normal LCD.
A tiny beginner Arduino module transformed into a huge working display!
