Printing text on an LCD display using switches

Blogmywiki takes on the challenge of printing text on an LCD display using switches:

There’s a YouTuber called the 8-Bit Guy who’s made a fantastic project where he gets text on an LCD display just using switches instead of a microcontroller or computer. He made his video in a nice box with chunky switches, and I thought I’d try and make one on a breadboard.

This was a mistake, but I did, just about, get it to work and it makes an interesting project to learn a bit about low level logic, binary maths, data representation and so on with some very simple and inexpensive parts. It’s a good gateway to building a more complex project like a breadboard computer, which I plan to do this winter and it will use a display just like this so it’s all good practice.

The little breadboard switches proved far too fiddly and are prone to flying out of the board.

See the video below and the post on blogmywiki.
