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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
