[M0TGN] wanted a device to generate practice code, so he built it around an Arduino. The device acts like an old commercial model, the Datong D70, although it can optionally accept an LCD screen ...

It can run on the Uno, Nano, Pro Micro, or even home-brew Arduino boards. He’s demonstrating the program with a Nokia 5110 LCD, but has also included code for the typical 2×16 LCD displays.

This module will investigate creating an interactive side-scrolling game using an Arduino. It will also provide experience with advanced usage of the 16x2 LCD screen and its scrolling capabilities.
