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.
