Control is via an Arduino Nano, with a few push buttons and a 16 x 2 LCD display for user feedback. Often, completing a first build will reveal all manner of limitations and drawbacks of a design.

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

[Ed] was tasked with adding push-button degaussing to an arcade cabinet’s CRT console. The display can be rotated to portrait mode for games that require it, but each time this is done, the m… ...
